    Objective: To analyze the influence of previous exposure to HBV on liver histology and treatment outcomes in chronic hepatitis C (CHC) patients. Study Design: Case control study. Place and Duration of Study: Rawalian Liver Clinic, Department of Medicine, Holy Family Hospital, Rawalpindi, from January 2011 to December 2012. Methodology: Medical records of CHC patients attending the Rawalian Liver Clinic were retrospectively analyzed. Virological and treatment responses along with histological changes were compared between cases (anti-HBc positive) and controls (anti-HBc negative). Significance was determined through chi-square test at p < 0.05. Results: Among the 592 CHC patients, 254 (42.9%) had serological evidence of a positive anti-HBc (cases) and 338 (57.1%), patients had negative anti-HBc (controls). No significant difference was found between ETR, SVR and treatment responses (n=220) between the two groups. Out of 65 patients whose liver biopsy data was available, cases were more likely to respond in the absence of fibrosis (63.2%, (n=24) vs. 36.8%, (n=14), p=0.001). The controls responded more in the presence of fibrosis (100% (n=9) vs. 0, p=0.001). There was no significant effect of anti-HBc positivity on grades of inflammation and consequent treatment response (p=0.14). Conclusion: There are a significant number of CHC patients with markers of previous HBV infection in Pakistani population. Previous HBV (anti-HBc positive) does not seem to have an adverse effect on liver histology and treatment responses in HBV infection. (author)

    In this study we use the maximum overlap discrete packet transform (MODWPT) to investigate residual effects on wheat biomass of fertigation treatments applied to a previous crop. The wheat crop covered nine subplots from a previous experiment on melon response to fertigation. Each subplot had previously received a different level of applied nitrogen. Many factors affect wheat biomass, causing it to vary at different spatial frequencies. We hypothesize that these will include residual effects from fertilizer application (at relatively low spatial frequencies) and the local influence of individual plants from the previous melon crop (at high frequency). To test this hypothesis we use the MODWPT to identify the dominant spatial frequencies of wheat biomass variation, and analyse the relationship to both the previous fertilizer application and the location of individual melon plants in the previous crop. The MODWPT is particularly appropriate for this because it allows us first to identify the key spatial frequencies in the wheat biomass objectively and to analyse them, and their relationship to hypothesized driving factors without any assumptions of uniformity (stationarity) of wheat-biomass variation. The results showed that the applied nitrogen dominated the wheat biomass response, and that there was a noticeable component of wheat-biomass variation at the spatial frequency that corresponds to the melon cropping. We expected wheat biomass to be negatively correlated with the position of melons in the previous crop, due to uptake of the applied nitrogen. The MODWPT, which allows us to detect changes in correlation between variables at different frequencies, showed that such a relationship was found across part of the experiment but not uniformly.

    Adults with Prader-Willi syndrome (PWS) have an increased proportion of sc fat mass compared with body mass index (BMI)-matched controls, but whether the genotype influences body composition and metabolic profile remains controversial. To assess body composition and metabolic features in adults with PWS, according to genetic subtype. In addition, the effect of previous GH treatment was assessed. Main Outcomes and Measures: Body composition (Dual Energy X-ray Absorptiometry) and metabolic parameters were compared in PWS adults (mean age, 25.5 ± 8.9 y) with deletion (n = 47) or uniparental disomy (UPD) (n = 26), taking into account GH treatment in childhood and/or adolescence. In subgroups, adipocyte size, fasting total ghrelin levels, and resting energy expenditure were measured, and hyperphagia was assessed by the Dykens Hyperphagia Questionnaire. In the whole sample, the deletion group had a higher BMI compared with UPD (40.9 ± 11.5 vs 34.6 ± 9.6 kg/m 2 , P = .02), but there was no difference between groups in percent body fat, metabolic profile, adipocyte size, resting energy expenditure, hyperphagia score, or ghrelin levels. In subjects previously treated with GH, BMI was not different between UPD and deletion groups (33.0 ± 9.7 vs 33.5 ± 11.1 kg/m 2 ). In addition, previous GH treatment was associated with decreased percent body fat and adipocyte volume only in the deletion group. A deletion genotype in adults with PWS is associated with increased BMI. GH treatment in childhood and/or adolescence limits this deleterious phenotypic effect with improved adiposity markers. This study suggests relationships between the molecular phenotype of PWS and adipose tissue development as well as sensitivity to GH.

  4. Five criteria for using a surrogate endpoint to predict treatment effect based on data from multiple previous trials.

    A surrogate endpoint in a randomized clinical trial is an endpoint that occurs after randomization and before the true, clinically meaningful, endpoint that yields conclusions about the effect of treatment on true endpoint. A surrogate endpoint can accelerate the evaluation of new treatments but at the risk of misleading conclusions. Therefore, criteria are needed for deciding whether to use a surrogate endpoint in a new trial. For the meta-analytic setting of multiple previous trials, each with the same pair of surrogate and true endpoints, this article formulates 5 criteria for using a surrogate endpoint in a new trial to predict the effect of treatment on the true endpoint in the new trial. The first 2 criteria, which are easily computed from a zero-intercept linear random effects model, involve statistical considerations: an acceptable sample size multiplier and an acceptable prediction separation score. The remaining 3 criteria involve clinical and biological considerations: similarity of biological mechanisms of treatments between the new trial and previous trials, similarity of secondary treatments following the surrogate endpoint between the new trial and previous trials, and a negligible risk of harmful side effects arising after the observation of the surrogate endpoint in the new trial. These 5 criteria constitute an appropriately high bar for using a surrogate endpoint to make a definitive treatment recommendation. Published 2017.

    Full Text Available Lipid damage evolution was analyzed in chilled Chilean jack mackerel (Trachurus murphyi previously treated with high hydrostatic pressure (HHP technology. Different pressure levels and pressure holding times were tested. In addition, fish corresponding to pre- and post-rigor mortis (RM stages were comparatively studied. Previous HHP treatment led to a marked lipid hydrolysis inhibition in chilled fish. Increasing the pressure level and pressure holding time led to a lower free fatty acid content, with the effect of pressure being more relevant. According to the analysis of different types of lipid oxidation indexes, no effect of the previous HHP treatment on the lipid oxidation development could be determined in chilled jack mackerel. Concerning the effect of the RM stage of raw fish, a higher primary and secondary lipid oxidation development was observed in fish corresponding to the post-RM condition throughout the chilled storage; although a definite effect on lipid hydrolysis could not be found.Se estudió la evolución de la alteración lipídica en jurel chileno (Trachurus murphyi refrigerado previamente tratado a altas presiones hidrostáticas (HHP. Se aplicaron distintos valores de presión y tiempo de presurización; asimismo, se analizó de forma comparativa la respuesta al proceso del pescado inicial en estados pre- y post-rigor mortis (RM. El tratamiento previo por HHP produjo inhibición de la hidrólisis lipídica en pescado refrigerado, siendo más intenso el efecto de la presión que el del tiempo de presurización. De acuerdo con el análisis de distintos índices de oxidación, no se concluyó un efecto determinante sobre la oxidación lipídica por parte del tratamiento previo de HHP. En relación al efecto del estado de RM del pescado inicial, se observó una oxidación primaria y secundaria mayor en jurel correspondiente a la condición post-RM durante la conservación en refrigeración; sin embargo, no se detectó un efecto

    Various approaches have been made over the years to classify psychotic patients according to inadequate treatment response, using terms such as treatment resistant or treatment refractory. Existing classifications have been criticized for overestimating positive symptoms; underestimating residual symptoms, negative symptoms, and side effects; or being to open for individual interpretation. The aim of this study was to present and evaluate a new method of classification according to treatment response and, thus, to identify patients in functional remission. A naturalistic, cross-sectional study was performed using patient interviews and information from patient files. The new classification method CANSEPT, which combines the Camberwell Assessment of Need rating scale, the Udvalg for Kliniske Undersøgelser side effect rating scale (SE), and the patient's previous treatment history (PT), was used to group the patients according to treatment response. CANSEPT was evaluated by comparison of expected and observed results. In the patient population (n = 123), the patients in functional remission, as defined by CANSEPT, had higher quality of life, fewer hospitalizations, fewer psychotic symptoms, and higher rate of workers than those with the worst treatment outcome. In the evaluation, CANSEPT showed validity in discriminating the patients of interest and was well tolerated by the patients. CANSEPT could secure inclusion of correct patients in the clinic or in research.

    To evaluate the influence of previous ectopic pregnancies (EP) and different EP treatment methods on in vitro fertilization-intracytoplasmic sperm injection (IVF-ICSI) outcomes. Retrospective cohort study. University-based reproductive medicine center. Women undergoing 51,268 fresh cycles of IVF-ICSI. In women who had had an EP before the IVF treatment and women who were diagnosed with fallopian disease without an EP (control group), division into three treatment subgroups: subgroup 1, conservative treatment; subgroup 2, salpingostomy; and subgroup 3 salpingectomy. Estimates of IVF-ICSI outcome and ovarian function based on number of antral follicles and rates of implantation, EP, clinical pregnancy, and delivery. For the experimental group and the control group, there were no statistically significant differences in the rates of implantation, clinical pregnancy, or delivery. However, the risk of recurrent EP was statistically significantly higher in the experimental group compared with the control group. There were no statistically significant differences in IVF-ICSI outcomes between the three treatment subgroups in terms of the basic antral follicle number or the dominant antral follicle numbers (>1.0 cm) after surgical treatment of EP. Our results suggest that women with a prior history of EP have a higher recurrence risk of EP after IVF in comparison with women with no history of EP. Previous EP has no effect on the main IVF-ICSI outcomes. For the treatment of EP, salpingostomy and salpingectomy do not statistically significantly affect ovarian function.

    The present study aims to investigate the effects of previous reproductive outcomes on the levels of depression, anxiety and perceived social support in subfertile women who conceived after in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) treatment. A prospective cohort study was developed. Data were collected on subfertile patients who conceived after IVF/ICSI treatment. All demographic and clinical data were recorded. The Edinburgh Postnatal Depression Scale, the State-Trait Anxiety Inventory-Y and the Multidimensional Scale of Perceived Social Support at 22 and 32 weeks of gestation and 15 days after delivery were completed. Data were analyzed comparing patients who conceived at their first IVF/ICSI cycle, after one unsuccessful ARTs cycle, and after multiple unsuccessful IVF/ICSI cycles. A significant increase in state anxiety and depression scores from 22 gestational weeks of gestation to 15 days after delivery was observed in patients who received multiple unsuccessful IVF/ICSI cycles compared with other groups. No significant difference in perceived social support was detected among groups. The differences in depression and anxiety scores remained consistent after controlling for perceived social support. A history of unsuccessful IVF/ICSI treatments seems to leave women more vulnerable in facing the duties of the new parental role. Such possibility underlies the importance of the availability of a psychological support for these women, even after a successful medical treatment for infertility.

    Odanacatib (ODN) is a selective cathepsin K inhibitor being developed to treat osteoporosis. The effects of ODN were evaluated on bone mineral density (BMD), biochemical markers of bone turnover, and safety in patients previously treated with alendronate. This was a randomized, double-blind, placebo-controlled, 24-month study. The study was conducted at private or institutional practices. Postmenopausal women (n = 243) ≥ 60 years of age with low BMD at the total hip, femoral neck, or trochanter (T-score ≤-2.5 but >-3.5 without prior fracture or ≤-1.5 but >-3.5 with prior fracture) on alendronate for ≥ 3 years. The intervention included ODN 50 mg or placebo weekly. The primary end point was percentage change from baseline of femoral neck BMD at month 24. BMD was assessed by dual-energy x-ray absorptiometry at baseline and 6, 12, and 24 months. Biochemical markers of bone turnover (serum C-telopeptides of type 1 collagen, urinary N-telopeptides of type 1 collagen, serum bone specific alkaline phosphatase, and serum N-terminal propeptide of type 1 collagen) were measured at baseline and 3, 6, 12, 18, and 24 months. In the ODN group, BMD changes from baseline at the femoral neck, trochanter, total hip, and lumbar spine at 24 months (1.7%, 1.8%, 0.8%, and 2.3%, respectively) were significantly different from the placebo group. ODN significantly decreased urinary N-telopeptides of type 1 collagen to creatinine ratio and significantly increased serum N-terminal propeptide of type 1 collagen compared with placebo. Serum C-telopeptides of type 1 collagen was unexpectedly increased with ODN treatment. The safety profile appeared similar between groups. ODN provided incremental BMD gains in osteoporotic women after alendronate treatment.

    The effect of GH deficiency (GHD) on the metabolic profile of acromegaly patients is unclear in patients previously treated for acromegaly, as are the efficacy and safety of GH treatment in this particular group. The aim of the study is to describe the characteristics of patients with severe GHD who were previously treated for acromegaly, and to investigate the effects of long-term GH treatment on cardiovascular risk factors and morbidity, compared with patients who were treated for a nonfunctioning pituitary adenoma (NFPA). A nationwide surveillance study. Sixty-five patients from the Dutch National Registry of Growth Hormone Treatment in Adults with previous acromegaly were compared with 778 patients with previous NFPA. Cardiovascular indices, including body composition, lipid profile, glucose metabolism, blood pressure, and morbidity were investigated. GHD patients with previous acromegaly had an unfavorable metabolic profile comparable with or more than GHD patients with previous NFPA. GH treatment led to improvement of the lipid profile in both groups, also after excluding patients using lipid-lowering medication. In patients with previous acromegaly, HbA1c levels increased more than in patients with previous NFPA (estimate 0.03, 95% CI 0.002-0.06, P=0.04). The risk for developing cardiovascular diseases was not different between the groups. The patients with GHD after previous acromegaly have an unfavorable metabolic profile comparable with patients with GHD after previous NFPA. In both groups, the lipid profile improves during GH treatment. Changes in glucose metabolism should be monitored closely. GH treatment in patients with GHD previously treated for acromegaly had no deleterious effect on cardiovascular morbidity. © 2014 European Society of Endocrinology.

    The incidence of breast cancer is increasing each year. Concomitantly, cosmetic breast augmentation has become the second most often performed cosmetic surgical procedure. As the augmented patient population ages, an increasing number of breast cancer cases among previously augmented women can be anticipated. The surgical treatment of these patients is controversial, with several questions remaining unanswered. Is breast conservation therapy feasible in this patient population and can these patients retain their implants? A retrospective review of all breast cancer patients with a history of previous augmentation mammaplasty who were treated at the Revlon/UCLA Breast Center between 1991 and 2001 was performed. During the study period, 58 patients were treated. Thirty patients (52 percent) were treated with a modified radical mastectomy with implant removal. Twenty-eight patients (48 percent) underwent breast conservation therapy, which consisted of lumpectomy, axillary lymph node dissection, and radiotherapy. Twenty-two of the patients who underwent breast conservation therapy initially retained their implants. Eleven of those 22 patients (50 percent) ultimately required completion mastectomies with implant removal because of implant complications (two patients), local recurrences (five patients), or the inability to obtain negative margins (four patients). Nine additional patients experienced complications resulting from their implants, including contracture, erosion, pain, and rupture. The data illustrate that breast conservation therapy with maintenance of the implant is not ideal for the majority of augmented patients. Breast conservation therapy with explantation and mastopexy might be appropriate for rare patients with large volumes of native breast tissue. Mastectomy with immediate reconstruction might be a more suitable choice for these patients.

    Congruency effects in distracter interference tasks are often smaller after incongruent trials than after congruent trials. However, the sources of such congruency sequence effects (CSEs) are controversial. The conflict monitoring model of cognitive control links CSEs to the detection and resolution of response conflict. In contrast, competing theories attribute CSEs to attentional or affective processes that vary with previous-trial congruency (incongruent vs. congruent). The present study s...

    An earlier randomized controlled trial (RCT) study showed that bee venom acupuncture (BVA) in combination with physiotherapy can be more effective in functional improvement and pain reduction in patients with adhesive capsulitis (AC). The objective of the current study was to examine the long-term effect of BVA in combination with physiotherapy on AC of the shoulder. Retrospective 1-year follow-up analysis of a previous RCT using a telephone interview method. Outpatient joint center at the Gang Dong Kyung Hee University Hospital of Seoul, Republic of Korea. A total of 192 patients had been enrolled in the previous study, and 124 of these were excluded from the current study. Sixty-eight patients who had been treated with combined BVA and physiotherapy for AC of the shoulder for 2 months were interviewed at approximately 1 year after treatment by telephone. Sixty of 68 patients were included in the follow-up analysis. Twenty received BV 1 treatment (1:10,000 concentration BVA plus physiotherapy), 22 received BV 2 treatment (1:30,000 concentration BVA plus physiotherapy), and 18 received control treatment (normal saline injection plus physiotherapy). The primary outcome measure was Shoulder Pain And Disability Index (SPADI) score. Secondary outcome measure was score on verbal rating scale for pain and patient satisfaction. Baseline characteristics of the groups did not significantly differ. SPADI scores at 1 year significantly differed between the BV 1 group and the control group (p=0.043). No significant differences were found in pain verbal rating scores after 1 year. Treatment satisfaction with therapy was also assessed, and the BV 1 and BV 2 groups showed significantly greater satisfaction compared with the control group. BVA combined with physiotherapy remains clinically effective 1 year after treatment and may help improve long-term quality of life in patients with AC of the shoulder.

    We performed post hoc analyses to evaluate the effect of humanized monoclonal antibody mepolizumab in patients with severe eosinophilic asthma previously treated with omalizumab. Data were collected from two randomized double-blind, placebo-controlled studies: MENSA (NCT01691521: 32-week treatment phase) and SIRIUS (NCT01691508: 24-week treatment phase). Active treatment was 75 mg intravenous mepolizumab (MENSA) or 100 mg subcutaneous mepolizumab (MENSA, SIRIUS). Patients had evidence of eosinophilic inflammation ≥150 cells/μl (at screening) or ≥300 cells/μl (during the previous year). Primary outcomes were the rate of exacerbations (MENSA) and the percentage reduction in oral corticosteroid (OCS) dose (SIRIUS). Other outcomes included lung function (forced expiratory volume in 1 s and morning peak expiratory flow), Asthma Control Questionnaire (ACQ-5), St George's Respiratory Questionnaire (SGRQ) scores, and safety. Overall, 576 patients were included from MENSA and 135 from SIRIUS, with 13% and 33% previously receiving omalizumab, respectively. In MENSA, mepolizumab reduced the rate of exacerbations by 57% (prior omalizumab) and 47% (no prior omalizumab) vs placebo. In SIRIUS, reductions in OCS use were comparable regardless of prior omalizumab use. Despite reducing chronic OCS use, mepolizumab also resulted in similar reductions in exacerbation rate relative to placebo in both subgroups. Asthma control and quality of life improved with mepolizumab vs placebo in both studies independent of prior omalizumab use, as shown by ACQ-5 and SGRQ scores. Adverse events were also comparable irrespective of prior omalizumab use. These post hoc analyses indicate that patients with severe eosinophilic asthma respond positively to mepolizumab regardless of prior use of omalizumab. © 2016 The Authors.

    We explored the addition of rituximab to high-dose cytarabine (ara-C), oxaliplatin (L-OHP), and dexamethasone [R-DHAOx], in resistant and relapsed patients with CD20-positive follicular non-Hodgkin's lymphoma. Twenty-two patients were included; they were treated previously with one to five chemotherapy regimens, including 13 patients who had also received rituximab. R-DHAOx consisted of rituximab, 375mg/m(2), day 1; dexamethasone, 40mg/d, days one to four; L-OHP, 130mg/m(2), day 1; and ara-C, 2000mg/m(2) every 12 h, day 2. Courses were repeated every 21 days for eight courses. Twenty-one patients (95%) achieved a complete response and one had a partial response. Responses were obtained in patients with and without resistance to prior treatment, either alone or combined with rituximab. The median follow-up time was 58.3 months (range, 8.7-92.6 months). Progression-free survival reached a plateau at 84% at 38.2 months. Only two of the 21 complete responders have relapsed. Tumor molecular markers disappeared in all 10 complete responders whose markers were found before treatment. Peripheral neuropathy related to the cumulative dose of L-OHP, and myelosuppression were the most prominent toxic effects. R-DHAOx is highly active for salvage treatment of patients with follicular non-Hodgkin's lymphoma, and it produces long-term antitumor efficacy. 2009 Elsevier Masson SAS. All rights reserved.

    Research has reported that a strong risk factor for traumatic injury is having a previous injury (i.e., recidivism). To date, the only study examining the relationship between recidivism and homicide reported strong associations, but was limited by possible selection bias. The current matched case-control study utilized coroner's data from 2004 to 2008. Subjects were linked to trauma registry data to determine whether the person had a previous traumatic injury. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for the association between homicide and recidivism. Homicide risk was increased for those having a previous traumatic injury (OR 1.81, 95% CI 1.09-2.99) or a previous intentional injury (OR 2.53, 95% CI 1.24-5.17). These results suggest an association between homicide and injury recidivism, and that trauma centers may be an effective setting for screening individuals for secondary prevention efforts of homicide through violence prevention programs. © 2014 American Academy of Forensic Sciences.

    Fingolimod (FTY) is licensed as a disease-modifying treatment in highly active relapsing-remitting multiple sclerosis. The aim of the study was to evaluate the efficacy and safety of FTY in a real-life setting and to explore the possible role of clinical and MRI parameters, including previous treatment type, in predicting its efficacy. Clinical and MRI data was collected on 127 patients assigned to treatment with FTY in six multiple sclerosis centers in Emilia-Romagna, Italy, between August 2011 and June 2013. During a mean follow-up period of 10 months (range 1-22), we observed a total of 47 relapses in 39 patients (30.7%); new T2 lesions or gadolinium-enhancing (Gd+) lesions were present at follow-up MRI in 32/71 patients (45%). Expanded disability status scale (EDSS) at the end of the follow-up period was not different when compared to the baseline EDSS. Serious adverse events occurred in three patients (2.4%). A higher proportion of patients previously treated with natalizumab showed clinical (41%) or MRI activity (54%). Previous treatment with natalizumab increased the risk of a relapse within 30 days (versus immunomodulatory drugs; OR: 4.3; p = 0.011) and at survival analysis (versus remaining patients; HR: 1.9; p = 0.046). Study limitations include a small population sample, a short observation period with variable timing of follow-up MRI and different baseline characteristics of patients previously treated with natalizumab compared to those treated with immunomodulatory drugs. This study confirms the efficacy of FTY in reducing relapse rate in patients previously treated with immunomodulatory drugs, while it seems to be less effective in patients discontinuing natalizumab. Due to the short duration of follow-up it is not possible to evaluate disability progression; however, no difference was observed between the groups.

    Eccentric training of the wrist extensors has been shown to be effective in treating chronic lateral epicondylosis. However, its efficacy in the treatment of medial epicondylosis has yet to be demonstrated. The objective of this study was to assess the effectiveness of a novel eccentric wrist flexor exercise added to standard treatment for chronic medial epicondylosis in patients who did not respond to previous therapeutic interventions for this disorder. 20. Patients (13 men, 7 women; age 49±12 yr) with chronic medial epicondylosis who had failed previous treatment for this disorder (physical therapy 7, cortisone injection 7, PRP 1, NSAIDS 15) were prescribed isolated eccentrics in addition to wrist stretching, ultrasound, cross-friction massage, heat and ice. The specific isolated eccentric wrist flexor strengthening exercise performed by the patients involved twisting a rubber bar (Flexbar, Hygenic Corportation, Akron OH) with concentric wrist flexion of the noninvolved arm and releasing the twist by eccentrically contracting the wrist flexors of the involved arm (3 × 15 twice daily). A DASH questionnaire was recorded at baseline and again after the treatment period. Treating clinicians were blinded to baseline DASH scores. Treatment effect was assessed using paired t-test. Based on previous work it was estimated that with a sample of 20 patients there would be 80% power to detect a 13 point improvement in DASH scores (ptennis (2), basketball (1), weight lifting (1), and general activities of daily living (2). There was a significant improvement in outcomes following the addition of isolated eccentrics (Pre DASH 34.7±16.2 vs. Post DASH 7.9±11.1, p<.001). For the 18 patients involved in sports, the sports module of the DASH score improved from 73.9±28.9 to 13.2±25.0, p<.001). Physical therapy visits ranged from 1-22 with an average of 12±6 and, average treatment duration of 6.1±2.5 wks (range 1-10). Home exercise program compliance was recorded for each

    The objective was to compare contraceptive method selection in women undergoing their first pregnancy termination versus women undergoing repeat pregnancy termination in an urban abortion clinic. We hypothesized that women undergoing repeat abortions will select highly effective contraceptives (intrauterine device, subdermal implant, tubal ligation) more often than patients undergoing their first abortion. We conducted a retrospective analysis of all women undergoing first-trimester surgical abortion at John H. Stroger, Jr., Hospital of Cook County from October 1, 2009, to October 31, 2011. We compared contraceptive method selection in the postabortion period after receipt of contraceptive counseling for 7466 women, stratifying women by history of no prior abortion versus one or more abortions. Of the 7466 women, 48.6% (3625) had no history of previous abortion. After controlling for age, race and number of living children, women with a history of abortion were more likely to select a highly effective method [odds ratio (OR) 1.19, 95% confidence interval (CI) 1.06-1.33]. Most significantly, having living children was the strongest predictor of a highly effective method with an OR of 3.17 (95% CI 2.69-3.75). In women having a first-trimester abortion, the factors most predictive of selecting a highly effective method for postabortion contraception include history of previous abortion and having living children. The latter holds true independent of abortion history. This paper is unique in its ability to demonstrate the high interest in highly effective contraceptive selection in high-risk, low-income women with prior abortion history. Efforts to integrate provision of highly effective methods of contraception for postabortion care are essential for the reduction of future unintended pregnancies. Copyright © 2015 Elsevier Inc.

    The purpose of this study was to evaluate the efficacy of CyberKnife for recurrent previously irradiated head and neck cancer. Thirty-one patients with recurrent previously irradiated head and neck cancer were treated with a CyberKnife from July 1999 to March 2002 at Okayama Kyokuto Hospital were retrospectively studied. The accumulated dose was 28-80 Gy (median 60 Gy). The interval between CyberKnife treatment and previous radiotherapy was 0.4-429.5 months (median 16.3 months). Primary lesions were nasopharynx: 7, maxillary sinus: 6, tongue: 5, ethmoid sinus: 3, and others: 1. The pathology was squamous cell carcinoma: 25, adenoid cystic carcinoma: 4, and others: 2. Symptoms were pain: 8, and nasal bleeding: 2. The prescribed dose was 15.0-40.3 Gy (median 32.3 Gy) as for the marginal dose. The response rate (complete response (CR)+partial response (PR)) and local control rate (CR+PR+no change (NC)) was 74% and 94% respectively. Pain disappeared for 4 cases, relief was obtained for 4 cases and no change for 2 cases and nasal bleeding disappeared for 2 cases for an improvement of symptoms. An adverse effects were observed as mucositis in 5 cases and neck swelling in one case. Prognosis of recurrent previously irradiated head and neck cancer was estimated as poor. Our early experience shows that CyberKnife is expected to be feasible treatment for recurrent previously irradiated head and neck cancer, and for the reduction adverse effects and maintenance of useful quality of life (QOL) for patients.

    If oversuppression of bone turnover explained the association between bisphosphonate use and atypical subtrochanteric femur fractures (AFF), this could be reversed with anabolic treatment such as teriparatide. We conducted a prospective, open-label study in patients previously treated with bisphosphonates who sustained AFF, examining the response to 24-month treatment with teriparatide on bone mineral density (BMD), trabecular bone score (TBS), bone turnover markers (BTM), and fracture healing as well as quantitative histomorphometry. We studied 14 patients. Baseline BMD, BTM, and TBS varied widely. On initial bone biopsies, 12 of 14 patients showed tetracycline labels, but mineralizing surface/bone surface was below published normal values in all but 2. Lumbar spine BMD increased significantly at month 24 (6.1% ± 4.3%, p teriparatide after prior bisphosphonate treatment. At month 24, fractures were healed in 6 patients, showed partial healing in 3, were unchanged in 2, and showed nonunion in 1. In a patient with two fractures, the fracture that occurred before teriparatide treatment was reported as healed, but the fracture that occurred while on treatment showed only partial healing. Bisphosphonate-treated patients who sustain AFF show heterogeneity of bone turnover. Treatment with teriparatide resulted in increases in BTM and lumbar spine BMD, as has been reported for patients without AFF. There was no significant effect of teriparatide on hip BMD, mineralizing surface to bone surface (MS/BS), or TBS and no consistent effect on fracture healing. In the context of a patient who has experienced an AFF after receiving bisphosphonate treatment, therapy with teriparatide for 24 months would be expected to increase BMD and BTM (and probably reduce the risk of fractures resulting from osteoporosis) but should not be relied on to aid in healing of the AFF. © 2017 American Society for Bone and Mineral Research. © 2017 American Society for Bone and Mineral Research.

    The goal of modern implant dentistry is to return patients to oral health in a rapid and predictable fashion, following a diagnostically driven treatment plan. If only a limited number of implants can be placed, or some fail and the prosthetic phase of implant dentistry is chosen to complete the patient's treatment, the final outcome may result in partial patient satisfaction and is commonly referred to as a "compromise." Previous All-on-4 implant treatment for the patient presented here resulted in a compromise, with an inadequate support system for the mandibular prosthesis and a maxillary complete denture with poor esthetics. The patient was unable to function adequately and also was disappointed with the resulting appearance. Correction of the compromised treatment consisted of bilateral inferior alveolar nerve elevation and repositioning without bone removal for lateral transposition, to gain room for rescue implants for a totally implant-supported and stabilized prosthesis. Treatment time to return the patient to satisfactory comfort, function, facial esthetics, and speech was approximately 2 weeks. The definitive mandibular prosthesis was designed for total implant support and stability with patient retrievability. Adequate space between the mandibular bar system and the soft tissue created a high water bridge effect for self-cleansing. Following a short interim mandibular healing period, the maxillary sinuses were bilaterally grafted to compensate for bone inadequacies and deficiencies for future maxillary implant reconstruction. © 2013 by the American College of Prosthodontists.

    Temozolomide (TMZ) is an alkylating agent primarily used to treat tumors of the central nervous system. We describe 2 patients with apparent TMZ-induced central diabetes insipidus. Using our institution's Research Patient Database Registry, we identified 3 additional potential cases of TMZ-induced diabetes insipidus among a group of 1545 patients treated with TMZ. A 53-year-old male with an oligoastrocytoma and a 38-year-old male with an oligodendroglioma each developed symptoms of polydipsia and polyuria approximately 2 months after the initiation of TMZ. Laboratory analyses demonstrated hypernatremia and urinary concentrating defects, consistent with the presence of diabetes insipidus, and the patients were successfully treated with desmopressin acetate. Desmopressin acetate was withdrawn after the discontinuation of TMZ, and diabetes insipidus did not recur. Magnetic resonance imaging of the pituitary and hypothalamus was unremarkable apart from the absence of a posterior pituitary bright spot in both of the cases. Anterior pituitary function tests were normal in both cases. Using the Research Patient Database Registry database, we identified the 2 index cases and 3 additional potential cases of diabetes insipidus for an estimated prevalence of 0.3% (5 cases of diabetes insipidus per 1545 patients prescribed TMZ). Central diabetes insipidus is a rare but reversible side effect of treatment with TMZ.

    In 2003, the uricosuric drug benzbromarone was withdrawn from the market. The first alternative drug of choice was the xanthine oxidase inhibitor allopurinol. The purpose was to (1) investigate the efficacy of allopurinol (standard dosage) compared with previous treatment with benzbromarone; and (2) investigate the combination therapy allopurinol-probenecid as an effective alternative treatment compared with previous benzbromarone treatment. A prospective, open study was carried out in a cohort of 51 gout patients who discontinued benzbromarone therapy because of market withdrawal. Patients were given 200-300 mg allopurinol (stage 1). When allopurinol failed to attain the target serum urate (sUr) levels probenecid 1,000 mg/day was added (stage 2). Treatment with benzbromarone monotherapy (range: 100-200 mg/day; mean 138 mg/day) resulted in 92% of patients reaching target levels sUr probenecid combination therapy, which resulted in 86% of patients attaining target sUr levels (after failure on allopurinol monotherapy), which was comparable to previous treatment with benzbromarone (p = 0.81). Decrease in sUr levels was 53[9]% (CI 95%: 48-58%), which was a non-significant difference compared to previous treatment with benzbromarone (p = 0.23). Benzbromarone is a very effective antihyperuricemic drug with 91% success in attainment of target sUr levels probenecid proves to be an effective treatment strategy for attaining sUr target levels (86% success).

    Objective: To determine the efficacy of peg-interferon-based therapy in patients refractory to previous conventional interferon-based treatment and factors predicting sustained viral response (SVR). Study Design: Analytical study. Place and Duration of Study: Medical Unit IV, Liaquat University Hospital, Jamshoro, from July 2009 to June 2011. Methodology: This study included consecutive patients of hepatitis C who were previously treated with conventional interferon-based treatment for 6 months but were either non-responders, relapsed or had virologic breakthrough and stage = 2 with fibrosis on liver biopsy. All eligible patients were provided peg-interferon at the dosage of 180 mu g weekly with ribavirin thrice a day for 6 months. Sustained Viral Response (SVR) was defined as absence of HCV RNA at twenty four week after treatment. All data was processed on SPSS version 16. Results: Out of 450 patients enrolled in the study, 192 were excluded from the study on the basis of minimal fibrosis (stage 0 and 1). Two hundred and fifty eight patients fulfilled the inclusion criteria and 247 completed the course of peg-interferon treatment. One hundred and sixty one (62.4%) were males and 97 (37.6%) were females. The mean age was 39.9 +- 6.1 years, haemoglobin was 11.49 +- 2.45 g/dl, platelet count was 127.2 +- 50.6 10/sup 3/ /mm/sup 3/, ALT was 99 +- 65 IU/L. SVR was achieved in 84 (32.6%). The strong association was found between SVR and the pattern of response (p = 0. 001), degree of fibrosis and early viral response (p = 0.001). Conclusion: Peg-interferon based treatment is an effective and safe treatment option for patients refractory to conventional interferon-based treatment. (author)

    Purpose The purpose of this study was to determine the effect of a prior gastrectomy on the difficulty of subsequent colonoscopy, and to identify the surgical factors related to difficult colonoscopies. Materials and Methods Patients with a prior gastrectomy who had undergone a colonoscopy between 2011 and 2014 (n=482) were matched (1:6) to patients with no history of gastrectomy (n=2,892). Cecal insertion time, intubation failure, and bowel clearance score were compared between the gastrectomy and control groups, as was a newly generated comprehensive parameter for a difficult/incomplete colonoscopy (cecal intubation failure, cecal insertion time >12.9 minutes, or very poor bowel preparation scale). Surgical factors including surgical approach, extent of gastrectomy, extent of lymph node dissection, and reconstruction type, were analyzed to identify risk factors for colonoscopy performance. Results A history of gastrectomy was associated with prolonged cecal insertion time (8.7±6.4 vs. 9.7±6.5 minutes; P=0.002), an increased intubation failure rate (0.1% vs. 1.9%; P<0.001), and a poor bowel preparation rate (24.7 vs. 29.0; P=0.047). Age and total gastrectomy (vs. partial gastrectomy) were found to be independent risk factors for increased insertion time, which slowly increased throughout the postoperative duration (0.35 min/yr). Total gastrectomy was the only independent risk factor for the comprehensive parameter of difficult/incomplete colonoscopy. Conclusions History of gastrectomy is related to difficult/incomplete colonoscopy performance, especially in cases of total gastrectomy. In any case, it may be that a pre-operative colonoscopy is desirable in selected patients scheduled for gastrectomy; however, it should be performed by an expert endoscopist each time. PMID:27752394

    Modified kaolin clays were used as adsorbents for SO(2) gas adsorptions. The clays were heated up to 900 °C previous to acid treatments with 0.5 N sulfuric acid solutions at boiling temperature during different times up to 1440 min. Equilibrium adsorption at 25 °C and 0.1 MPa was carried out by using a volumetric apparatus. The samples were characterized by chemical analysis, X-ray diffraction and infrared analysis. The heating of the clays followed by acid treatment improved the adsorption capacity of the kaolin clays. The presence of amorphous silica and hydroxyl in the final products improved SO(2) adsorption capacity. Better properties for SO(2) adsorption were found in kaolin rich in not well ordered kaolinite clay mineral. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2014-01-01

    Purpose: Using a database of prior treated patients, it is possible to predict the dose to critical structures for future patients. Automatic treatment planning speeds the planning process by generating a good initial plan from predicted dose values. Methods: A SQL relational database of previously approved treatment plans is populated via an automated export from Pinnacle 3 . This script outputs dose and machine information and selected Regions of Interests as well as its associated Dose-Volume Histogram (DVH) and Overlap Volume Histograms (OVHs) with respect to the target structures. Toxicity information is exported from Mosaiq and added to the database for each patient. The SQL query is designed to ask the system for the lowest achievable dose for a specified region of interest (ROI) for each patient with a given volume of that ROI being as close or closer to the target than the current patient. Results: The additional time needed to calculate OVHs is approximately 1.5 minutes for a typical patient. Database lookup of planning objectives takes approximately 4 seconds. The combined additional time is less than that of a typical single plan optimization (2.5 mins). Conclusions: An automatic treatment planning interface has been successfully used by dosimetrists to quickly produce a number of SBRT pancreas treatment plans. The database can be used to compare dose to individual structures with the toxicity experienced and predict toxicities before planning for future patients.

    Full Text Available The effect of flaxseeds (Linum usitatissimum on rancidity development in frozen whole mackerel (Scomber scombrus was studied. For it, fresh mackerel were dipped in flaxseeds aqueous extract during 60 min, frozen at –80 ºC during 24 hours and kept frozen (–20 ºC up to 12 months. Sampling was carried out on the initial material and at months 1, 3, 5, 7, 9 and 12 of frozen storage at –20 ºC. A parallel experiment with non treated fish was carried out in the same conditions. Rancidity development was measured by several biochemical indices (free fatty acids, peroxides, conjugated dienes and trienes, secondary oxidation products and lipoxygenase activity and complemented by the sensory analysis (skin, flesh odour, consistency and flesh appearance. As a result of the previous antioxidant treatment, peroxides showed to breakdown faster (pSe ha estudiado el efecto del lino (Linum usitatissimum en el desarrollo de rancidez en caballa entera congelada (Scomber scombrus.

    Full Text Available Objective: To identify the main causing factors of fear and anxiety of children previously to dental treatment. Methods: A descriptive and qualitative study held in the municipal district of Acaraú - CE with 10 children aged 4 to 6 years old, who did not present strong pain between August and September, 2006. At first, we applied the modified VPT (Venham Picture Test, an instrument containing a set of figures of children in different emotional states, which were presented to each child so that he pointed to what he considered to be further identified at the time. The second test, held before the consultation, consisted in asking to the children to free-hand draw the dental office, the dentist and auxiliary personnel asking to each child: what do you think about the dental office and the dentist? The drawings were submitted to idiographic analysis and categorized in units of significance for interpretation. Results: Three children on VPT and nine children on the drawings presented an increased level of anxiety. Causing factors such as the motor (high speed rotation, tooth extraction and white clothes could be found. Final considerations: By means of drawing we were able to efficiently obtain results in identifying some factors that cause fear and anxiety to the child patient. The modified VPT showed to be quick, easy to apply and acceptable to children, but sometimes was contradictory with the drawings.

    In patients with unresectable colorectal liver metastases (CLM) resistant to first-line chemotherapy, the impact of cetuximab therapy on resectability is unknown. This study was performed to determine the post-cetuximab resectability rate and to examine postoperative outcomes for these heavily pretreated patients. From February 2004 to April 2006, we evaluated 151 patients with unresectable CLM resistant to initial chemotherapy and subsequently treated with systemic cetuximab. Resectability rates, patient outcomes, and tumoral and nontumoral liver pathology were assessed. A total of 27 patients underwent surgery after a median of six cycles of cetuximab + irinotecan (20 of 27), oxaliplatin (four of 27), or both (one of 27). Eighteen patients (67%) had experienced treatment failure after at least two lines of chemotherapy before cetuximab. Twenty-five of the 27 patients who had surgery underwent hepatectomy: nine of 133 patients who were treated completely at our institution (resectability rate, 7%) and 16 of 18 patients who were referred from other institutions after systemic cetuximab therapy. Postoperative mortality was 3.7% (one of 27), with a complication rate of 50%. Histopathologic liver abnormalities were found in nine patients (36%), without specific lesions attributable to cetuximab. After median follow-up of 16 months, 23 of 25 patients who underwent resection (92%) were alive, and 10 patients (40%) were disease free. Median overall (OS) and progression-free survival (PFS) from initiation of cetuximab therapy were 20 and 13 months, respectively. For CLM refractory to conventional chemotherapy, combination therapy with cetuximab increases resectability rates without increasing operative mortality or liver injury. The median OS and PFS of 20 and 13 months, respectively, suggest that this novel oncosurgical strategy benefits patients with previously refractory disease who respond subsequently to cetuximab.

    Full Text Available Previous research has shown that participants' strategy choices can be influenced by the previously-used strategy. This'perseveration effect' has been demonstrated both after a repeated use of the previous strategy (e.g., Schillemans, Luwel, Bulté, Onghena, & Verschaffel, 2009, but also after a single use of the previous strategy (Lemaire & Lecacheur, 2010. In the present study, we tested whether this perseveration effect would be stronger after a repeated than after a single previous strategy application. We were able to replicate the perseveration effect but we did not find evidence for an influence of the number of previous strategy applications on the strength of this effect. An additional cluster analysis revealed that only about one third of the participants was susceptible for the perseveration effect. The theoretical, methodological, and educational implications of these results are discussed.

    Explanatory factors for the observed neurocognitive impairment in early-stage bipolar I disorder (BD-I) have received little attention. The current study investigated neurocognitive functioning in first-treatment (FT) BD-I compared to FT schizophrenia (SCZ), and healthy controls (HCs), and the effect of history of psychosis and previous episodes in the two clinical groups. A total of 202 FT patients with BD-I (n = 101) and SCZ spectrum disorder (n = 101), in addition to HCs (n = 101), were included. A comprehensive neurocognitive test battery was used to assess verbal learning and memory, executive functioning, processing speed, and attention and working memory. Neurocognitive functioning and the effect of history of psychosis and number of previous episodes were analyzed using separate multivariate analyses of variance and correlation analysis. FT patients with BD-I performed intermediately between FT SCZ spectrum patients and HCs on all measures. Compared to HCs, FT BD-I showed impaired functioning across all neurocognitive domains. No differences in neurocognitive functioning were observed in psychotic versus nonpsychotic FT patients with BD-I. With the exception of an association between number of manic episodes and two measures of executive function in FT BD-I, no associations were found between number of episodes and neurocognitive performance. Neurocognitive impairments were present in FT BD-I, and were not explained by history of psychosis or number of previous psychotic or depressive episodes. There were indications that executive function could be associated with number of previous manic episodes. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    In this preliminary study, we examined the effect of acupressure, acupuncture and moxibustion (oriental treatments) to prevent of the relapse/deterioration of perinatal depression in women with pregnancy-related anxiety and previous depression. Between 2014 and 2016, there were 48 women with pregnancy-related anxiety and previous depression who had delivery at ≥ 22 weeks' gestation in our institute. Of these, oriental treatments were performed in eight and two women (totally 10, 21%) during pregnancy and postpartum, respectively. One of the 10 (10%) who received oriental treatments admitted depressive symptoms during pregnancy or postpartum, while 18 of the rest 38 who did not receive oriental treatments admitted depressive symptoms (47%, P = 0.065). The oriental treatments may be useful for pregnant women who need perinatal mental health care.

    To analyze time to return to sport, functional outcomes, and recurrences of the modified Latarjet procedure without capsulolabral repair in athletes with recurrent anterior shoulder instability after a failed previous operative stabilization. We included athletes with recurrent anterior shoulder instability with a previous failed operative stabilization treated with the modified Latarjet procedure without capsulolabral repair with a minimum of 2-year follow-up. Return to sports, range of motion, the Rowe score, a visual analog scale for pain in sport activity, and the Athletic Shoulder Outcome Scoring System were used to assess functional outcomes. Recurrences were also evaluated. The postoperative bone block position and consolidation were assessed with computed tomography. Between June 2008 and June 2015, 68 athletes were treated with the modified Latarjet procedure without capsulolabral reconstruction for recurrent shoulder instability after a previous failed stabilization surgery. The mean follow-up was 44 months (range, 24-108 months), and the mean age at the time of operation was 26.8 years (range, 17-35 years). All the patients returned to sports, and 95% returned to the same sport they practiced before the surgery, all to the same level. No significant difference in shoulder range of motion was found between preoperative and postoperative results. The Rowe score, visual analog scale, and Athletic Shoulder Outcome Scoring System showed statistical improvement after operation (P Latarjet without capsulolabral repair produced excellent functional outcomes with most athletes returning to sport at the same level they had before the surgery without recurrences.

    Chronic obstructive pulmonary disease (COPD) is an inflammatory lung disease largely associated with cigarette smoke exposure (CSE) and characterized by pulmonary and extrapulmonary manifestations, including systemic inflammation. Liver growth factor (LGF) is an albumin-bilirubin complex with demonstrated antifibrotic, antioxidant, and antihypertensive actions even at extrahepatic sites. We aimed to determine whether short LGF treatment (1.7 μg/mouse ip; 2 times, 2 wk), once the lung damage was established through the chronic CSE, contributes to improvement of the regeneration of damaged lung tissue, reducing systemic inflammation. We studied AKR/J mice, divided into three groups: control (air-exposed), CSE (chronic CSE), and CSE + LGF (LGF-treated CSE mice). We assessed pulmonary function, morphometric data, and levels of various systemic inflammatory markers to test the LGF regenerative capacity in this system. Our results revealed that the lungs of the CSE animals showed pulmonary emphysema and inflammation, characterized by increased lung compliance, enlargement of alveolar airspaces, systemic inflammation (circulating leukocytes and serum TNF-α level), and in vivo lung matrix metalloproteinase activity. LGF treatment was able to reverse all these parameters, decreasing total cell count in bronchoalveolar lavage fluid and T-lymphocyte infiltration in peripheral blood observed in emphysematous mice and reversing the decrease in monocytes observed in chronic CSE mice, and tends to reduce the neutrophil population and serum TNF-α level. In conclusion, LGF treatment normalizes the physiological and morphological parameters and levels of various systemic inflammatory biomarkers in a chronic CSE AKR/J model, which may have important pathophysiological and therapeutic implications for subjects with stable COPD.

    Full Text Available Abstract Background Aggressive non-melanoma skin cancer (deeply infiltrating, recurrent, and morphea form lesions are therapeutically challenging because they require considerable tissue loss and may demand radical disfiguring surgery. Interferons (IFN may provide a non-surgical approach to the management of these tumors. The aim of this work was to evaluate the effect of a formulation containing IFNs-α and -γ in synergistic proportions on patients with recurrent, advanced basal cell (BCC or squamous cell skin carcinomas (SCSC. Methods Patients with extensive, recurrent, resistant to other procedures BCC or SCSC received the IFN formulation peri- and intralesionally, three times per week for 3 weeks. They had been previously treated with surgery and/or radiotherapy or chemotherapy. Thirteen weeks after the end of treatment, the original lesion sites were examined for histological evidence of remaining tumor. Results Sixteen elder (median 70 years-old patients were included. They beared 12 BCC and 4 SCSC ranging from 1.5 to 12.5 cm in the longest dimension. At the end of treatment 47% CR (complete tumor elimination, 40% PR (>30% tumor reduction, and 13% stable disease were obtained. None of the patients relapsed during the treatment period. The median duration of the response was 38 months. Only one patient with complete response had relapsed until today. Principal adverse reactions were influenza-like symptoms well known to occur with interferon therapy, which were well tolerated. Conclusion The peri- and intralesional combination of IFNs-α and -γ was safe and showed effect for the treatment of advanced, recurrent and resistant to previous treatments of BCC and SCSC in elder patients. This is the first report of such treatment in patients with advance non-melanoma skin cancer. The encouraging result justifies further confirmatory trials.

    Treatment with prolonged-release oxycodone/naloxone (PR OXN) has been shown to improve opioid induced constipation (OIC) in constipated patients. This publication reports on a real-life observational study investigating the efficacy of PR OXN with regard to bowel function in patients switching to PR OXN from WHO step 1, step 2 and step 3 opioids. Patients with chronic pain experiencing insufficient pain relief and/or unacceptable side effects were switched to PR OXN and monitored in this observational study with respect to efficacy regarding bowel function and efficacy regarding pain relief in comparison with previous analgesic therapy. A patient was considered a responder with respect to efficacy if this assessment was "slightly better", "better" or "much better" compared with previous therapy. Bowel function index, pain intensity, quality of life, laxative medication use, and safety analgesic were also evaluated. A total of 1338 patients (mean [SD] age 64.3 [14.9], 63% female) were observed for 43 [3-166] days (median [range]) during treatment with PR OXN. Overall response rate regarding bowel function efficacy was 82.5%. Patients with symptoms of constipation at study entry obtained a clinically relevant improvement of the bowel function index (BFI) within the first 2 weeks of PR OXN treatment. Non-constipated patients at study entry maintained normal bowel function despite switching to treatment with the opioid PR OXN. In conclusion, treatment with PR OXN results in a significant and clinically relevant improvement of bowel function. During the observation of the treatment with PR OXN patients reported an improvement of quality of life (QoL). More interestingly, non-constipated patients maintained a normal bowel function, showing prevention of constipation despite the use of an opioid.

    Full Text Available Application of organic manure in organic farming and long-term mineralization may lead to residual effects on the succeeding crop. So, residual effects of combined cattle manure and urea fertilizer of previous crop (black cumin on growth and yield of pea were examined in a randomized complete block design. Treatments included of  cattle manure (CM, urea (U, three ratios of CM+U full dose application (2:1; 1:1; 1:2 and three ratios of CM+U split application (2:1; 1:1; 1:2, and unfertilized control to previous crop (black cumin in 2012. Pea planted without any fertilizer in 2013. There was no significant difference between control and residual of urea treatment for some parameters including dry matter in flowering stage, plant nitrogen and phosphorus concentration, plant height, yield components, grain yield and biological yield of pea. Biological and grain yields were greater under both residual of cattle manure treatment and integrated treatments compared to residual of urea treatment. The highest grain yield (4000 kg ha-1 was observed in residual of CM:U full dosed application treatment, to the extent that grain yield in this treatment indicated a 1.5-fold increase in comparison with residual of urea treatment. The highest biological yield (8325 kg ha-1 was obtained in residual of CM treatment, though it was not significant different from that of residual of CM:U (1:2 treatments. In general, although residual of urea fertilizer did not leave a notable effect on pea production, but production of this crop relying on residual of cattle manure deems effective to lowering of fertilization cost and ameliorating environmental contaminations.

  19. Preoperative electrocardiography: its cost-effectiveness in detecting abnormalities when a previous tracing exists.

    Rabkin, S W; Horne, J M

    1979-01-01

    In 812 patients who underwent routine preoperative electrocardiography a mean of 24.6 months after undergoing electrocardiography at the same institution, the frequency of new abnormalities was estimated to evaluate the cost-effectiveness of this procedure prior to an operation. New abnormalities were judged to be either relevant or irrelevant to the assessment of operative risk, depending upon their previously demonstrated correlation with operative and postoperative morbidity and mortality. Since new abnormalities, especially new relevant abnormalities, were found to be relatively infrequent, the cost-effectiveness of routine preoperative electrocardiography was considered to be low. The evidence suggested that when a previous tracing exists preoperative electrocardiography is most clearly indicated for patients who are 60 years of age or older or whose previous tracing exhibited abnormalities. However, further research is required to develop more sensitive and specific protocols, and to evaluate the role of repeat electrocardiography in clinical decision-making. PMID:111793

    1997-05-01

    Making a blood donation, especially for first-time donors, can be a stressful experience. These feelings of stress may inhibit donors from returning. This paper applies stress theory to this particular problem. The effects of a stress management intervention (the provision of music) and previous donor experience were examined in relation to pre- and post-donation mood, environmental appraisals and coping behaviour. Results indicated that the provision of music had detrimental effects on environmental appraisals for those who have donated up to two times previously, but beneficial effects for those who had donated three times before. These effects were, to an extent, moderated by coping processes but not perceived control. It is recommended that the provision of music is not used as a stress management technique in the context of blood donation.

  1. Correction of Large Oro-antral Communications From Previously Failed Implant Treatment: Reconstruction of Hard and Soft Tissues.

    2018-02-01

    As dental implants become more popular for the treatment of partial and total edentulism and treatment of "terminal dentitions," techniques for the management of the atrophic posterior maxillae continue to evolve. Although dental implants carry a high success rate long term, attention must be given to the growing numbers of revisions or retreatment of cases that have had previous dental implant treatment and/or advanced bone replacement procedures that, due to either poor patient compliance, iatrogenic error, or poor quality of the pre-existing alveolar and/or soft tissues, have led to large osseous defects, possibly with deficient soft-tissue volume. In the posterior maxillae, where the poorest quality of bone in the oral cavity exists, achieving regeneration of the alveolar bone and adequate volume of soft tissue remains a complex procedure. This is made even more difficult when dealing with loss of dental implants previously placed, aggressive bone reduction required in various implant procedures, and/or residual sinus infections precluding proper closure of the oral wound margins. The purpose of this article is to outline a technique for the total closure of large oro-antral communications, with underlying osseous defects greater than 15 mm in width and 30 mm in length, for which multiple previous attempts at closure had failed, to achieve not only the reconstruction of adequate volume and quality of soft tissues in the area of the previous fistula, but also total regeneration of the osseous structures in the area of the large void.

    This study assessed the role of habits and previous behavior in predicting fruit consumption as well as their additional predictive contribution besides socio-demographic and motivational factors. In the literature, habits are proposed as a stable construct that needs to be controlled for in longitudinal analyses that predict behavior. The aim of this study is to provide empirical evidence for the inclusion of either previous behavior or habits. A random sample of 806 Dutch adults (>18 years) was invited by an online survey panel of a private research company to participate in an online study on fruit consumption. A longitudinal design (N = 574) was used with assessments at baseline and after one (T2) and two months (T3). Multivariate linear regression analysis was used to assess the differential value of habit and previous behavior in the prediction of fruit consumption. Eighty percent of habit strength could be explained by habit strength one month earlier, and 64% of fruit consumption could be explained by fruit consumption one month earlier. Regression analyses revealed that the model with motivational constructs explained 41% of the behavioral variance at T2 and 38% at T3. The addition of previous behavior and habit increased the explained variance up to 66% at T2 and to 59% at T3. Inclusion of these factors resulted in non-significant contributions of the motivational constructs. Furthermore, our findings showed that the effect of habit strength on future behavior was to a large extent mediated by previous behavior. Both habit and previous behavior are important as predictors of future behavior, and as educational objectives for behavior change programs. Our results revealed less stability for the constructs over time than expected. Habit strength was to a large extent mediated by previous behavior and our results do not strongly suggest a need for the inclusion of both constructs. Future research needs to assess the conditions that determine direct

    1991-01-01

    Rat cervical spinal cord was X-ray irradiated at doses of 15, 18, 20 and 26 Gy. Approximately the same part of the spinal cord was heated by means of a 434 MHz microwave applicator 90 days later. After treatment, animals were observed for 18 months, for expression of neurological complications. These could either be result of the heat or of the radiation treatment. The time course showed 3 distinct peaks in the incidence of neurological symptoms. The 1st peak was due to the acute response to hyperthermia. The ED 50 value for neurological complications one day after treatment at 42.3±0.4 o C was 74 ±2 min. Previous X-ray irradiation of spinal cord with 18, 20 and 26 Gy reduced ED 50 to 57±7,65±4 and 55±5 min (12-26% of control), resp. Recovery from heat-induced neurological complications was diminished in previously irradiated animals. The 2nd peak (150-300 days after X-rays) concerned expression of 'early-delayed' radiation damage. Hyperthermia given in 90 days after irradiation did not influence either the percentage of animals with paralysis or the latent period. Neurological symptoms developing after day 300 were due to the late delayed radiation response. Significant difference was not observed in data on paralysis induced by radiation alone or radiation followed by heat. The late radiation-induced minor neurological symptoms, were however, influenced by retreatment with heat. (author). 30 refs., 6 figs., 3 tabs

    The number of multidrug-resistant tuberculosis patients is increasing each year in many countries all around the globe. Malaysia has no exception in facing this burdensome health problem. We aimed to investigate the factors that contribute to the occurrence of multidrug-resistant tuberculosis among Malaysian tuberculosis patients. An unmatched case-control study was conducted among tuberculosis patients who received antituberculosis treatments from April 2013 until April 2014. Cases are those diagnosed as pulmonary tuberculosis patients clinically, radiologically, and/or bacteriologically, and who were confirmed to be resistant to both isoniazid and rifampicin through drug-sensitivity testing. On the other hand, pulmonary tuberculosis patients who were sensitive to all first-line antituberculosis drugs and were treated during the same time period served as controls. A total of 150 tuberculosis patients were studied, of which the susceptible cases were 120. Factors found to be significantly associated with the occurrence of multidrug-resistant tuberculosis are being Indian or Chinese (odds ratio 3.17, 95% confidence interval 1.04-9.68; and odds ratio 6.23, 95% confidence interval 2.24-17.35, respectively), unmarried (odds ratio 2.58, 95% confidence interval 1.09-6.09), living in suburban areas (odds ratio 2.58, 95% confidence interval 1.08-6.19), are noncompliant (odds ratio 4.50, 95% confidence interval 1.71-11.82), were treated previously (odds ratio 8.91, 95% confidence interval 3.66-21.67), and showed positive sputum smears at the 2nd (odds ratio 7.00, 95% confidence interval 2.46-19.89) and 6th months of treatment (odds ratio 17.96, 95% confidence interval 3.51-91.99). Living in suburban areas, positive sputum smears in the 2nd month of treatment, and was treated previously are factors that independently contribute to the occurrence of multidrug-resistant tuberculosis. Those with positive smears in the second month of treatment, have a history of previous

    Oxaliplatin (L-OHP) is a platinum complex that possesses activity against human and murine cells in vitro and in vivo, including colorectal carcinoma-derived cell lines, and cells that have been selected for resistance to cisplatin. We report two consecutive phase II trials of L-OHP for treatment of patients with advanced colorectal carcinoma. Fifty-eight patients were entered in study I, and 51 patients in study II. All of the patients had tumor progression when they were treated, prior to their enrollment, with a fluoropyrimidine-containing regimen. In both trials treatment consisted of L-OHP, 130 mg/m2, by i.v. infusion for two hours; the treatment was repeated every 21 days. Response to therapy: Study I: Fifty-five patients were assessed for response. The response rate was 11% (95% CI, 0.03-0.19). Study II: All 51 patients were assessed for response. The response rate was 10% (95% CI, 0.017-0.18). The overall response rate for the 106 evaluated patients was 10% (95% CI, 0.046-0.16). Times to disease progression in responders were 4, 4, 4.5+, 5, 5, 6, 6, 6, 6+, 9, and 13 months. The dose-limiting toxic effect was sensory peripheral neuropathy. The incidence of severe peripheral neuropathy grades was: Study I: grade 3, 23% of patients, and grade 4, 8% of patients. Severe neuropathy had a favorable course in all of the patients who had long-term neurologic follow-up. Diarrhea and myeloid impairment were minor. L-OHP produced modest, but definite antitumor activity in patients with advanced colorectal carcinoma who were previously resistant to chemotherapy including fluoropyrimidines. Toxicity is within acceptable limits of tolerance at the dose and schedule of oxaliplatin used in this trial.

    This study examined the effects of previous outcomes on subsequent choices in a probabilistic-choice task. Twenty-four rats were trained to choose between a certain outcome (1 or 3 pellets) versus an uncertain outcome (3 or 9 pellets), delivered with a probability of .1, .33, .67, and .9 in different phases. Uncertain outcome choices increased with the probability of uncertain food. Additionally, uncertain choices increased with the probability of uncertain food following both certain-choice outcomes and unrewarded uncertain choices. However, following uncertain-choice food outcomes, there was a tendency to choose the uncertain outcome in all cases, indicating that the rats continued to “gamble” after successful uncertain choices, regardless of the overall probability or magnitude of food. A subsequent manipulation, in which the probability of uncertain food varied within each session as a function of the previous uncertain outcome, examined how the previous outcome and probability of uncertain food affected choice in a dynamic environment. Uncertain-choice behavior increased with the probability of uncertain food. The rats exhibited increased sensitivity to probability changes and a greater degree of win–stay/lose–shift behavior than in the static phase. Simulations of two sequential choice models were performed to explore the possible mechanisms of reward value computations. The simulation results supported an exponentially decaying value function that updated as a function of trial (rather than time). These results emphasize the importance of analyzing global and local factors in choice behavior and suggest avenues for the future development of sequential-choice models. PMID:23205915

    In Sub-Saharan Africa, the fight against tuberculosis (TB) has encountered a great challenge because of the emergence of drug resistant TB strains and the high prevalence of HIV infection. The aim of this meta-analysis was to determine the association of drug-resistant TB with anti-TB drug treatment history and HIV co-infection. After electronic based literature search in the databases of Medline, HINARI, EMBASE and the Cochrane library, article selection and data extraction were carried out. HIV co-infection and previous history of TB treatment were used as predictors for the occurrence of any anti-TB drug resistant or multiple drug resistant TB (MDR-TB). The risk ratios for each included study and for the pooled sample were computed using the random-effects model. Heterogeneity test, sensitivity analyses and funnel plots were also done. The pooled analysis showed that the risk of developing drug-resistant TB to at least one anti-TB drug was about 3 times higher in individuals who had a previous history of anti-TB treatment than new TB cases. The risk of having MDR-TB in previously anti-TB treated TB cases was more than 5-fold higher than that of new TB cases. Resistance to Ethambutol and Rifampicin was more than fivefold higher among the previously treated with anti-TB drugs. However, HIV infection was not associated with drug-resistant TB. There was a strong association of previous anti-TB treatment with MDR-TB. Primary treatment warrants special emphasis, and screening for anti-TB drugs sensitivity has to be strengthened.

    Background: The objective of the present investigation was to compare the effect of neoadjuvant irradiation on the microvascular anastomosis in cervical bundle using an experimental model in rats. Methods: One hundred forty male Sprague–Dawley rats were allocated into 4 groups: group I, control, arterial microanastomosis; group II, control, venous microanastomosis; group III, arterial microanastomosis with previous irradiation (20 Gy); and group IV, venous microanastomosis with previous irradiation (20 Gy). Clinical parameters, technical values of anastomosis, patency, and histopathological parameters were evaluated. Results: Irradiated groups (III and IV) and vein anastomosis groups (II and IV) showed significantly increased technical difficulties. Group IV showed significantly reduced patency rates (7/35) when compared with the control group (0/35). Radiotherapy significantly decreased the patency rates of the vein (7/35) when compared with the artery (1/35). Groups III and IV showed significantly reduced number of endothelial cells and also showed the presence of intimal thickening and adventitial fibrosis as compared with the control group. Conclusion: Neoadjuvant radiotherapy reduces the viability of the venous anastomosis in a preclinical rat model with a significant increase in the incidence of vein thrombosis. PMID:27975009

    This study investigates the effects of anticoagulant therapy on pregnancy outcomes in 204 patients with thrombophilia and previous poor obstetric outcomes. Patients with poor obstetric history (pre-eclampsia, intrauterine growth retardation, fetal death, placental abruption, recurrent pregnancy loss) and having hereditary thrombophilia were included in this study. Poor obstetric outcomes were observed more frequently in patients who had not taken anticogulant therapy compared with treated group. Live birth rate, gestational age at birth and Apgar scores were significantly higher in the treated group when compared with the untreated group. There were no significant differences in terms of birthweight, mode of delivery and admission rates to the neonatal intensive care unit (NICU). Low-molecular-weight heparin (LMWH) plus acetylsalicylic acid (ASA) had higher gestational age at birth, Apgar scores, live birth rate and a lower abortion rates when compared with controls; in contrast, no significant difference was observed in terms of birthweight, mode of delivery, obstetric complications and admission rates to NICU. There were no significant differences between control group and both LMWH only and ASA only groups in terms of gestational age at birth, Apgar scores, birthweight, mode of delivery, obstetric complications and admission rates to NICU. Only LMWH group had higher live birth rate as compared with control group. The use of only ASA did not seem to affect the perinatal complication rates and outcomes. In conclusion, anticoagulant therapy with both LMWH and ASA seems to provide better obstetric outcomes in pregnant women with thrombophilia and previous poor obstetric outcomes.

    Full Text Available Thirty-two ewes were used to study how the ovarian response to a superovulatory treatment determines quality of oocytes recovered from ovaries after embryo collection, and their developmental capacity after in vitro maturation (IVM and fertilization (IVF. Ewes were superovulated, and seven days after oestrus, embryos were collected and ewes divided into three groups: (+ +, n=19, ewes responding to the treatment with embryos collected after flushing; (+ –, n=8, ewes responding, but only oocytes were found; and (– –, n=5, ewes not responding to the treatment and no embryos collected. Ovaries were recovered and oocytes collected from the three groups. A significant effect of the response to the treatment was observed for oocyte quality, so that (– – ewes presented the higher number of oocytes per ewe (p<0.001. Total number of oocytes selected for IVM and IVF was significantly higher in the same group, in comparison with (+ + and (+ – (p<0.001. Group (+ – ewes presented the lowest maturation (p<0.001, fertilization (p<0.05 and cleavage rates (p<0.001. In conclusion, the ovarian response to a superovulatory treatment determines the number and quality of the oocytes recovered 7 days after the oestrus induced by the hormonal treatment. In vitro techniques could be an important tool to increase embryo production by particular ewes when they are not able to produce a significant amount of in vivo embryos.

    Full Text Available Immediate treatment of first-episode psychosis is essential in order to achieve a positive outcome. However, Indonesian psychiatric patients often delay accessing health services, the reason for which is not yet fully understood. The current study aimed to understand patterns of treatment seeking and to reveal determinants of the delay in accessing psychiatric care among first-time user psychotic patients. Qualitative interviews were conducted with sixteen family members who accompanied the patients to a psychiatric hospital. Many families expressed beliefs that mental illness appertains to village sickness and not hospital sickness; therefore, they usually take the patients to traditional or religious healers before taking them to a health professional. They also identified various factors that potentially delay accessing psychiatric treatment: low literacy and beliefs about the cause of the illness, stigmatisation, the role of extended family, financial problems, and long distance to the psychiatric hospital. On the other hand, the family mentioned various factors related to timely help seeking, including being a well-educated family, living closer to health facilities, previous experience of successful psychotic therapy, and having more positive symptoms of psychosis. The findings call for mental health awareness campaigns in the community.

    The aim of this work was to identify, synthesize and evaluate the results of randomized controlled trials examining the effects of resistance training on performance indicators in previously trained endurance runners. A database search was carried out in PubMed, Science Direct, OvidSPMedLine, Wiley, Web of Science, ProQuest and Google Scholar. In accordance with the PRISMA checklist, 18 published articles dated prior to May 2016 involving 321 endurance runners were reviewed using the PEDro scale. Resistance training led to general improvements in muscular strength, running economy, muscle power factors, and direct performance in distances between 1,500 and 10,000 m. Such improvements were not accompanied by a significant increase in body mass or signs of overtraining. However, improvements did not occur in all cases, suggesting that they might depend on the specific characteristics of the resistance training applied. Although current evidence supports the effectiveness of resistance training to improve performance in already trained endurance runners, the methodological inconsistencies identified suggest that the results should be interpreted with caution. Future studies ought to investigate the benefits of resistance training in endurance runners while considering the existence of possible differentiated effects based on the specific characteristics of the resistance training carried out.

    The purpose of this study was to evaluate the analgesic effect of botulinum toxin A (BoNTA) injections in patients with myofascial pain syndrome (MPS) who were previously treated with the local infiltration of anesthetic and steroids (LIAS). The study included a retrospective phase and a longitudinal open-label prospective phase, which were conducted on consecutive patients with MPS previously treated with the local infiltration of anesthetic (levobupivacaíne 0.25%) and steroids (triamcinolone 40 mg). Eligible patients were treated with a single intramuscular injection of BoNTA (Botox; Allergan, Inc., Irvine, CA). The treatment efficacy was determined according to the degree of pain relief obtained. Eighty-two patients met the inclusion/exclusion criteria and were included in the study. Successful results were obtained for 32 (39.0%) and 30 (36.6%) patients, during treatment with BoNTA and LIAS, respectively. The mean (standard deviation) length of the analgesic effect was significantly longer with BoNTA (29.6 [SD = 17.7] weeks) than with LIAS (8.5 [SD = 6.4] weeks), P local infiltration of anesthetic and steroids who then received a single injection of BoNTA experienced significantly reduced pain for a relatively long time.

    The association between the previous history of endometriosis and obstetric outcomes is still ambiguous. This study aimed to evaluate the effects of previous history of operatively diagnosed endometriosis on pregnancy outcomes. A total of 98 primiparous women who had been diagnosed with endometriosis by previous laparoscopic surgery were included in this retrospective cohort study. Pregnancy outcomes were compared between these women (study group) who had a live birth and 300 women without endometriosis (control group) who had a live birth. In the study group, the pregnancy outcomes of 74 women who conceived naturally (no assisted reproductive technology [ART] subgroup) were simultaneously compared with 24 women who conceived by ART (ART subgroup). Miscarriage was observed in 23 of 98 women with endometriosis (23.5%). There were 75 women who had a live birth after laparoscopic diagnosis of endometriosis in the study group eventually. On multivariate analysis, the postpartum hemorrhage rate increased significantly in the study group when compared with the control group (adjusted odds ratio: 2.265, 95% confidence interval: 1.062, 4.872; P = 0.034). There was an upward tendency of developing other pregnancy-related complications, such as preterm birth, placental abruption, placenta previa, cesarean section, fetal distress/anemia, and others in the study group than in the control group. However, the differences showed no statistical significance. Within the study group, the occurrence rate of postpartum hemorrhage and preterm birth was both higher in the ART subgroup than in the no ART subgroup. The differences both had statistical significance (44.4% vs. 17.5%, P = 0.024 and 27.8% vs. 1.8%, P = 0.010, respectively). At the same time, median (interquartile range) for gestational age at delivery in the ART subgroup was significantly shorter than that in the no ART subgroup (38 weeks [36-39 weeks] vs. 39 weeks [38-40 weeks]; P = 0.005). Endometriosis may affect obstetric

    Our aim was to demonstrate the effect of insicion of renal parenchyma during open renal stone surgery (ORSS) on percutaneous nephrolithotomy (PNL) outcomes. Patients with history of ORSS who underwent PNL operation between June 2005 and June 2015 were analyzed retrospectively. Patients were divided into two groups according to their type of previous ORSS. Patients who had a history of ORSS with parenchymal insicion, such as radial nephrotomies, anatrophic nephrolithotomy, lower pole resection, and partial nephrectomy, were included in Group 1. Other patients with a history of open pyelolithotomy were enrolled in Group 2. Preoperative characteristics, perioperative data, stone-free status, and complications were compared between the groups. Stone-free status was defined as complete clearance of stone(s) or presence of residual fragments smaller than 4 mm. The retrospective nature of our study, different experience level of surgeons, and lack of the evaluation of anesthetic agents and cost of procedures were limitations of our study. 123 and 111 patients were enrolled in Groups 1 and 2, respectively. Preoperative characteristics were similar between groups. In Group 1, the mean operative time was statistically longer than in Group 2 (p=0.013). Stone-free status was significantly higher in Group 2 than in Group 1 (p=0.027). Complication rates were similar between groups. Hemorrhage requiring blood transfusion was the most common complication in both groups (10.5% vs. 9.9%). Our study demonstrated that a history of previous ORSS with parenchymal insicion significantly reduces the success rates of PNL procedure.

    Growing from demands for accountability and research-based practice in the field of education, there is recent focus on developing standards for the implementation and analysis of single-case designs. Effect size methods for single-case designs provide a useful way to discuss treatment magnitude in the context of individual intervention. Although a standard effect size methodology does not yet exist within single-case research, panel experts recently recommended pairing regression and non-parametric approaches when analyzing effect size data. This study compared two single-case effect size methods: the regression-based, Allison-MT method and the newer, non-parametric, Tau-U method. Using previously published research that measured the Words read Correct per Minute (WCPM) variable, these two methods were examined by comparing differences in overall effect size scores and rankings of intervention effect. Results indicated that the regression method produced significantly larger effect sizes than the non-parametric method, but the rankings of the effect size scores had a strong, positive relation. Implications of these findings for research and practice are discussed. Copyright © 2014 Society for the Study of School Psychology. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Objective To evaluate the responses of C-terminal telopeptide (CTX and serum osteocalcin after the first 4 months of treatment with strontium ranelate (SR and demonstrate their association with long-term bone density changes. Subjects and Methods A sample of 13 postmenopausal women with osteoporosis was analyzed (mean age 65 ± 7.7 years, who were treated with SR for an average of 2.56 ± 0.86 years. All patients had undergone previous treatment with bisphosphonates for an average period of 4.88 ± 2.27 years. Serum CTX and osteocalcin levels were determined before and after four months of treatment with SR. Bone mineral density in the lumbar spine and femoral neck were obtained before and after treatment with SR. Results We observed an average increase of 53.7% in the CTX levels, and 30.7% in the osteocalcin levels. The increase in bone markers was associated with a mean 4.8% increase in lumbar spine bone mineral density (BMD from 0.820 to 0.860 g/cm 2 ( T -score from –2.67 to –1.92; P= 0.001, after 2.5 years of treatment with SR. Conclusion These data suggest an anabolic effect of SR on postmenopausal women who were previously treated with long-term bisphosphonates.

    Two groups of Romanian children were compared on spectral power and coherence in the electroencephalogram (EEG) in early childhood. One group consisted of previously institutionalized children who had been randomly assigned to a foster care intervention at a mean age of 23 months. The second group had been randomized to remain in institutional care. Because of a policy of noninterference, a number of these children also experienced placement into alternative family care environments. There were minimal group differences between the foster care and institutionalized groups in EEG power and coherence across all measured frequency bands at 42 months of age. However, age at foster care placement within the foster care group was correlated with certain measures of EEG power and coherence. Earlier age at foster care placement was associated with increased alpha power and decreased short-distance EEG coherence. Further analyses separating age at placement from duration of intervention suggest that this effect may be more robust for EEG coherence than EEG band power. Supplementary analyses examined whether the EEG measures mediated changes in intellectual abilities within the foster care children, but no clear evidence of mediation was observed.

    The effect of sodium benzoate on the quality attributes of improved tamarind beverage during storage was investigated. Tamarind beverages were produced according to a previously reported improved method, with or without chemical preservatives (100 mg/100 mL sodium benzoate). Tamarind beverage produced according to traditional processing method served as the control. The tamarind beverages were stored for 4 months at room (29 ± 2°C) and refrigerated (4-10°C) temperatures. Samples were analyzed, at regular intervals, for chemical, sensory, and microbiological qualities. Appearance of coliforms or overall acceptability score of 5.9 was used as deterioration index. The control beverages deteriorated by 2nd and 10th days at room and refrigerated temperatures, respectively. Improved tamarind beverage produced without the inclusion of sodium benzoate was stable for 3 and 5 weeks at room and refrigerated temperatures, respectively. Sodium benzoate extended the shelf life of the improved tamarind beverage to 6 and 13 weeks, respectively, at room and refrigerated temperatures.

    Therapeutic effect of bone marrow transplantation (BMT) and blood transfusion on different groups of rats subjected to various doses of total body irradiation (TBI) was studied. In the control group, 80 rats that received TBI of 8,9,10,11 and 12 Gy died between 3∼14 days. In the second group, 67 rats that received the same doses of irradiation were treated with BMT. Except that 8 rats died from lung hemorrhages at 4∼6 days after TBI. 85% of these animals (500/59) showed hemopoietic engraftment. The survival rates of 8, 9, 10, 11 and 12 Gy subgroups at 90 days after BMT were 90%, 56%, 56%, 25% and 0% respectively. In the third group, 82 rats receive TBI and blood transfusion prior to BMT. Except that 8 rats subjected to 11∼12 Gy irradiation died from lung hemorrhage at 4∼6 days after BMT, 97% of these animals (72/74) showed hemopoietic engraftment. The 90-day survival rates of 8, 9, 10, 11 and 12 Gy subgroups were 93%, 80%, 80%, 60% and 6% respectively. The 90-day survival rate of 50 rats subjected to 9∼11 Gy TBI and treated with blood transfusion and BMT, was 72%, while that 47 rats treated simply with BMT was only 42%. These results showed clearly that previous blood transfusion could increase the rate of hemopoietic engraftment, reduce the incidence if rejection, and raise the survival rate

    The aim of this study was to examine the effect of an enrichment programme in motor, technical and tactical basketball skills, when accounting for the age of youth sport specialisation. Seventy-six college students (age: M = 20.4, SD = 1.9) were allocated according to three different paths: (i) non-structured (n = 14), (ii) early specialisation (n = 34), and (iii) late specialisation (n = 28), according to information previously provided by the participants about the quantity and type of sporting activities performed throughout their sporting careers. Then, the participants of each path were randomly distributed across control and experimental groups. Variables under study included agility, technical skills circuit, as well as tactical actions performed in a 4-on-4 full-court basketball game. The results indicated improvements in the early and late specialisation paths namely in the experimental training groups. However, the late specialisation path revealed larger benefits, in contrast with the non-structured path, which showed less sensitivity to the enrichment programme, mostly sustained in physical literacy and differential learning. Higher improvements were observed in agility, and also in reducing the number of unsuccessful actions performed during the game. Overall, this study provided evidence of how early sports experiences affect basketball skill acquisition and contribute to adapt to new contexts with motor and technical-tactical challenges. In addition, a path supported by late specialisation might present several advantages in sport performance achievement.

    The impact of previous abdominal surgeries on the need for conversion to open surgery and on short-term outcomes during/after laparoscopic colectomy was retrospectively investigated. This retrospective cohort study was conducted from December 1996 through December 2009. This study was conducted at Osaka Medical College Hospital. A total of 1701 consecutive patients who had undergone laparoscopic resection of the colon and rectum were classified as not having previous abdominal surgery (n = 1121) or as having previous abdominal surgery (n = 580). Short-term outcomes were recorded, and risk factors for conversion to open surgery were analyzed. There were no significant differences in operative time, blood loss, number of lymph nodes removed, or conversion rate between the groups. The rate of inadvertent enterotomy was significantly higher in the previous abdominal surgery group than in the not having previous abdominal surgery group (0.9% versus 0.1%; p = 0.03), and the postoperative recovery time was significantly longer in the previous abdominal surgery group than in the not having previous abdominal surgery group. Ileus was more frequent in the previous abdominal surgery group than in the not having previous abdominal surgery group (3.8% versus 2.1%; p = 0.04). Significant risk factors for conversion to open surgery were T stage ≥3 (OR, 2.81; 95% CI, 1.89-3.75), median incision (OR, 4.34; 95% CI, 1.23-9.41), upper median incision (OR, 2.78; 95% CI, 1.29-5.42), lower median incision (OR, 1.82; 95% CI, 1.09-3.12), and transverse colectomy (OR, 1.76; 95% CI, 1.29-2.41). The incidence of successfully completed laparoscopic colectomy after previous abdominal surgery remains high, and the short-term outcomes are acceptable.

    In a naturally mated cycle, ova and viable embryo number as well as embryo size were assessed on Day 4, 10, 14, 18, and 30 of gestation in Romney ewes (n = 38-44 per gestational group). For Days 4-18 of gestation, embryos were recovered by flushing the reproductive tract after slaughtering of the ewe. Ovulation rate was determined by counting the number of corpora lutea present on both ovaries. For the Day 30 group, number of ovulations was measured by laparoscopic examination of the ovaries at Day 9-12 of the cycle, and number of embryos present was determined by ultrasound examination at approximately Day 30 of pregnancy. Most of embryo loss occurred before Day 14 of gestation with 6% loss before Day 4, and 12% loss between Day 4 and 14 of gestation. A similar proportion of viable embryos per number of ova ovulated were recovered on Day 14 and 18 (82%) and Day 30 (81%) of gestation. Fertilization failure was estimated at 1%. Conceptus and embryo size was most variable on Day 14, representing a period of rapid growth (conceptus length ± standard deviation); Day 4 (169 ± 8 μm), Day 10 (379 ± 93 μm), Day 14 (23 ± 32 mm), Day 18 (embryo length ± standard deviation; 5.0 ± 0.7 mm). Vaccination with commercially available fertility vaccines targeting androstenedione (Androvax and Ovastim) in previous seasons resulted in reduced conceptus size compared with controls. However, no difference in the proportion of viable embryos was observed between treatments, signifying maternal tolerance for considerable variation at this stage of development. Furthermore, the finding that most of loss occurs within the first 14 days of gestation highlights the importance of both oocyte quality and the uterine environment for the embryo to successfully overcome the challenges leading up to and including pregnancy recognition in the ewe.

    Treatment of displaced periprosthetic acetabular fractures in elderly patients. The goal is to stabilize an acetabular fracture independent of the fracture pattern, by inserting the custom-made roof-reinforcement plate and starting early postoperative full weight-bearing mobilization. Acetabular fracture with or without previous hemi- or total hip arthroplasty. Non-displaced acetabular fractures. Watson-Jones approach to provide accessibility to the anterior and supraacetabular part of the iliac bone. Angle-stable positioning of the roof-reinforcement plate without any fracture reduction. Cementing a polyethylene cup into the metal plate and restoring prosthetic femoral components. Full weight-bearing mobilization within the first 10 days after surgery. In cases of two column fractures, partial weight-bearing is recommended. Of 7 patients with periprosthetic acetabular fracture, 5 were available for follow-up at 3, 6, 6, 15, and 24 months postoperatively. No complications were recognized and all fractures showed bony consolidation. Early postoperative mobilization was started within the first 10 days. All patients except one reached their preinjury mobility level. This individual and novel implant is custom made for displaced acetabular and periprosthetic fractures in patients with osteopenic bone. It provides a hopeful benefit due to early full weight-bearing mobilization within the first 10 days after surgery. In case of largely destroyed supraacetabular bone or two-column fractures according to Letournel additional synthesis via an anterior approach might be necessary. In these cases partial weight bearing is recommended.

    The purpose of this study is to describe our policy in selecting different types of anaesthesia and anterior tension-free techniques for the repair of recurrent inguinal hernias previously treated by anterior approach and to evaluate early and late outcomes. The medical records of 111 patients who underwent recurrent inguinal hernia repair by anterior approach in the period 2000-2013 were reviewed. Fifty patients (45 %) were over 70 years old and 63 (56.7 %) had one or more co-morbidities. Hernias with large defects were the most frequently observed (59.5 %), and no-mesh techniques were the most frequent failed repair (75.7 %). Different anterior tension-free techniques and types of anaesthesia were used, depending on hernia and patient characteristics. Seventy-three patients (65.8 %) were operated on an outpatient basis. Mean follow-up period was 89 months (range 10-183). No perioperative deaths, medical events, or visceral injuries were recorded. Early postoperative complications occurred in 11 patients: 4 haematomas (3.6 %), 5 seromas (4.5 %), 1 superficial wound infection (0.9 %) and 1 ischemic orchitis (0.9 %). Late complications consisted in 3 cases of chronic moderate pain (3.2 %) and 2 re-recurrences (2.1 %). Recurrent inguinal hernia previously treated by open anterior technique can be repaired using the same approach, often on an outpatient basis, with a low rate of recurrence and postoperative complications. To be safe and effective, the repair should be performed by appropriately trained surgeons, well versed in the use of different types of anaesthesia and surgical techniques depending on patient and hernia characteristics.

  16. Long- term effects of previous experience determine nutrient discrimination abilities in birds

    Full Text Available Abstract Background Foraging behaviour is an essential ecological process linking different trophic levels. A central assumption of foraging theory is that food selection maximises the fitness of the consumer. It remains unknown, however, whether animals use innate or learned behaviour to discriminate food rewards. While many studies demonstrated that previous experience is a strong determinant of complex food choices such as diet mixing, the response to simple nutritional stimuli, such as sugar concentrations, is often believed to be innate. Results Here we show that previous experience determines the ability to track changes in sugar composition in same-aged individuals of a short-lived migratory songbird, the garden warbler (Sylvia borin. Although birds received identical foods for seven months prior to the experiment, wild-caught birds achieved higher sugar intake rates than hand-raised birds when confronted with alternative, differently coloured, novel food types. Hand-raised and wild birds did not differ in their initial colour selection or overall food intake, but wild birds were quicker to adjust food choice to varying sugar intake. Conclusion Over a period of at least seven months, broader previous experience translates into a higher plasticity of food choice leading to higher nutrient intake. Our results thus highlight the need to address previous long-term experience in foraging experiments. Furthermore, they show that hand-raised animals are often poor surrogates for testing the foraging behaviour of wild animals.

    The AVERROES double-blinded, randomized trial demonstrated that apixaban reduces the risk of stroke or systemic embolism (SSE) by 55% compared with aspirin without an increase in major bleeding in patients with atrial fibrillation either who previously tried but failed vitamin K antagonists (VKA) therapy or who were expected to be unsuitable for VKA therapy. In this pre-specified analysis, we explored the consistency of the results in the subgroup of patients who tried but failed VKA therapy. Of 5599 patients, 2216 (40%) had previously failed VKA treatment [main reasons: poor international normalized ratio (INR) control 42%, refusal 37%, bleeding on VKA 8%]. Compared with those expected to be unsuitable for VKA therapy, those who had previously failed were older, more often male, had higher body mass index, more likely to have moderate renal impairment and a history of stroke and less likely to have heart failure or to be medically undertreated. The effects of apixaban compared with aspirin were consistent in those who previously failed and those who were expected to be unsuitable, for both SSE (P interaction 0.13) and major bleeding (P interaction 0.74) and were also consistent among different subgroups of patients who had previously failed VKA therapy defined by reasons for unsuitability, age, sex, renal function, CHADS2 score, aspirin dose, duration, indication, and quality of INR control of prior VKA use. The efficacy and safety of apixaban compared with aspirin is consistent in subgroups of patients who have previously attempted but failed VKA therapy, irrespective of the reason for discontinuation.

    Despite theoretical associations, there is a lack of empirical studies on the axiological basis of sexual liberalism-conservatism. Two studies demonstrated important associations between these constructs for young adults. In Study 1, participants were 353 undergraduate students with a mean age of 20.13 (SD = 1.84), who completed the Sexual Liberalism-Conservatism Scale and the Basic Values Survey. In Study 2, participants were 269 undergraduate students, with a mean age of 20.3 (SD = 1.82), who completed a social desirability scale in addition to Study 1 instruments. Results showed how values can predict sexual liberalism-conservatism after controlling for social desirability. Attitudes towards one's own sexual behavior were more conservative whereas attitudes towards other's sexual behavior were more liberal. Gender was not a significant predictor of sexual attitudes whereas previous sexual experience showed a significant association to this construct. In general, results corroborated previous findings, showing that participants with a tendency to present socially desirable answers also tended to present themselves as sexually conservative.

  1. The emotional harbinger effect: Poor context memory for cues that previously predicted something arousing

    Science.gov (United States)

    Mather, Mara; Knight, Marisa

    2009-01-01

    A key function of memory is to use past experience to predict when something important might happen next. Indeed, cues that previously predicted arousing events (emotional harbingers) garner more attention than other cues. However, the current series of five experiments demonstrates that people have poorer memory for the context of emotional harbinger cues than of neutral harbinger cues. Participants first learned that some harbinger cues (neutral tones or faces) predicted emotionally arousing pictures and others predicted neutral pictures. Then they studied associations between the harbinger cues and new contextual details. They were worse at remembering associations with emotional harbingers than with neutral harbingers. Memory was impaired not only for the association between emotional harbingers and nearby digits but also for contextual details that overlapped with or were intrinsic to the emotional harbingers. However, new cues that were inherently emotionally arousing did not yield the same memory impairments as the emotional harbingers. Thus, emotional harbinger cues seem to suffer more from proactive interference than do neutral harbinger cues, impairing formation of new associations with cues that previously predicted something arousing.

    1980-01-01

    The radioprotective action of interferon (IF) in increasing the survival time of mice lethally irradiated 24 h previously was evaluated. A single intraperitoneal injection of 30,000 units of IF administered 1 day following a LD 100 dose of irradiation significantly prolonged the mean survival time of the animals. Multiple inoculations of IF given 1,3, and 5 days after irradiation only slightly increased the survival time over that observed in mice receiving single injections. Marked decreases in total number of splenocytes were observed in irradiated mice as well as in the mice receiving postirradiation IF therapy, whereas total peripheral white blood cell counts were not appreciably changed when evaluated 3 days after X irradiation. Natural lymphocyte killer activity of splenocytes from irradiated animals receiving IF was significantly increased, suggesting that the protective action of IF could be partially attributable to the boosting of some depressed immune functions

    Recent interest in the antidepressant and anti-stress effects of subanesthetic doses of ketamine, an NMDA receptor antagonist, has identified mechanisms whereby ketamine reverses the effect of stress, but little is known regarding the prophylactic effect ketamine might have on future stressors. Here we investigate the prophylactic effect of ketamine against neurochemical and behavioral changes that follow inescapable, uncontrollable tail shocks (ISs) in Sprague Dawley rats. IS induces increased anxiety, which is dependent on activation of serotonergic (5-HT) dorsal raphe nucleus (DRN) neurons that project to the basolateral amygdala (BLA). Ketamine (10 mg/kg, i.p.) administered 2 h, 1 week, or 2 weeks before IS prevented the increased extracellular levels of 5-HT in the BLA typically produced by IS. In addition, ketamine administered at these time points blocked the decreased juvenile social investigation produced by IS. Microinjection of ketamine into the prelimbic (PL) region of the medial prefrontal cortex duplicated the effects of systemic ketamine, and, conversely, systemic ketamine effects were prevented by pharmacological inhibition of the PL. Although IS does not activate DRN-projecting neurons from the PL, IS did so after ketamine, suggesting that the prophylactic effect of ketamine is a result of altered functioning of this projection. The reported data show that systemic ketamine, given up to 2 weeks before a stressor, blunts behavioral and neurochemical effects of the stressor. The study also advances understanding of the mechanisms involved and suggests that ketamine acts at the prelimbic cortex to sensitize neurons that project to and inhibit the DRN.

    2012-12-01

    Full Text Available CONTEXT: Non-derivative surgical techniques are the treatment of choice for the control of upper digestive tract hemorrhages after schistosomotic portal hypertension. However, recurrent hemorrhaging due to gastroesophagic varices is frequent. OBJECTIVE: To evaluate the outcome of treatment based on embolization of the left gastric vein to control the reoccurrence of hemorrhages caused by gastroesophagic varices in patients with schistosomiasis previously submitted to non-derivative surgery. METHODS: Rates of reoccurrence of hemorrhages and the qualitative and quantitative reduction of gastroesophagic varices in patients undergoing transhepatic embolization of the left gastric vein between December 1999 and January 2009 were studied based on medical charts and follow-up reports. RESULTS: Seven patients with a mean age of 39.3 years underwent percutaneous transhepatic embolization of the left gastric vein. The mean time between azigoportal disconnections employed in combination with splenectomy and the percutaneous approach was 8.4 ± 7.3 years, and the number of episodes of digestive hemorrhaging ranged from 1 to 7 years. No episodes of reoccurrence of hemorrhaging were found during a follow-up period which ranged from 6 months to 7 years. Endoscopic postembolization studies revealed reductions in gastroesophagic varices in all patients compared to preembolization endoscopy. CONCLUSIONS: Percutaneous transhepatic embolization of the left gastric vein in patients with schistosomiasis previously submitted to surgery resulted in a decrease in gastroesophagic varices and was shown to be effective in controlling hemorrhage reoccurrence.

  10. Decomposing experience-driven attention: opposite attentional effects of previously predictive cues

    2016-01-01

    A central function of the brain is to track the dynamic statistical regularities in the environment—such as what predicts what over time. How does this statistical learning process alter sensory and attentional processes? Drawing upon animal conditioning and predictive coding, we developed a learning procedure that revealed two distinct components through which prior learning-experience controls attention. During learning, a visual search task was used in which the target randomly appeared at one of several locations but always inside an encloser of a particular color—the learned color served to direct attention to the target location. During test, the color no longer predicted the target location. When the same search task was used in the subsequent test, we found that the learned color continued to attract attention despite the behavior being counterproductive for the task and despite the presence of a completely predictive cue. However, when tested with a flanker task that had minimal location uncertainty—the target was at the fixation surrounded by a distractor—participants were better at ignoring distractors in the learned color than other colors. Evidently, previously predictive cues capture attention in the same search task but can be better suppressed in a flanker task. These results demonstrate opposing components—capture and inhibition—in experience-driven attention, with their manifestations crucially dependent on task context. We conclude that associative learning enhances context-sensitive top-down modulation while reduces bottom-up sensory drive and facilitates suppression, supporting a learning-based predictive coding account.

The introduction of BRAF/MEK inhibitor combinations has yielded significant increases in PFS and OS for melanoma. However, at present, no direct comparisons between different BRAF/MEK combinations have been conducted. In light of this, an indirect treatment comparison was performed between two BRAF/MEK inhibitor combination therapies for metastatic melanoma, dabrafenib plus trametinib and vemurafenib plus cobimetinib, in order to understand the relative efficacy and toxicity profiles of these therapies. A systematic literature search identified two randomized trials as suitable for indirect comparison: the coBRIM trial of vemurafenib plus cobimetinib versus vemurafenib and the COMBI-v trial of dabrafenib plus trametinib versus vemurafenib. The comparison followed the method of Bucher et al. and analyzed both efficacy (overall survival [OS], progression-free survival [PFS], and overall response rate [ORR]) and safety outcomes (adverse events [AEs]). The indirect comparison revealed similar efficacy outcomes between both therapies, with no statistically significant difference between therapies for OS (hazard ratio [HR] 0.94, 95% confidence interval [CI] 0.68 - 1.30), PFS (HR 1.05, 95% CI 0.79 - 1.40), or ORR (risk ratio [RR] 0.90, 95% CI 0.74 - 1.10). Dabrafenib plus trametinib differed significantly from vemurafenib plus cobimetinib with regard to the incidence of treatment-related AE (RR 0.92, 95% CI 0.87 - 0.97), any AE grade ≥3 (RR 0.71, 95% CI 0.60 - 0.85) or dose interruption/modification (RR 0.77, 95% CI 0.60 - 0.99). Several categories of AEs occurred significantly more frequently with vemurafenib plus cobimetinib, while some occurred significantly more frequently with dabrafenib plus trametinib. For severe AEs (grade 3 or above), four occurred significantly more frequently with

    Full Text Available BACKGROUND: This study was performed to evaluate the safety and efficacy of paclitaxel with cisplatin as salvage therapy in patients previously treated with gemcitabine and cisplatin (G/C for advanced transitional cell carcinoma (TCC of the urothelial tract. METHODS: Twenty-eight patients with metastatic or locally advanced TCC who had received prior G/C chemotherapy were enrolled. All patients received paclitaxel (175 mg/m2 and cisplatin (60 mg/m2 every 3 weeks for eight cycles or until disease progression. RESULTS: The median age was 61 years (range, 43–83 years, and the median Eastern Cooperative Oncology Group performance status was 1 (range, 0–2. The overall response rate was 36% [95% confidence interval (95% CI = 18–54], with three complete responses and seven partial responses. The median time to progression was 6.2 months (95% CI = 3.9–8.5, and the median overall survival was 10.3 months (95% CI = 6.1–14.1. The most common Grade 3/4 nonhematologic and hematologic toxicities were emesis (10 of 28 patients; 36% and neutropenia (5 of 110 cycles; 5%. CONCLUSIONS: Salvage chemotherapy with paclitaxel and cisplatin displayed promising results with tolerable toxicity profiles in patients with metastatic or locally advanced TCC who had been pretreated with G/C.

    Full Text Available Exercise training (ET is an important intervention for chronic diseases such as diabetes mellitus (DM. However, it is not known whether previous exercise training intervention alters the physiological and medical complications of these diseases. We investigated the effects of previous ET on the progression of renal disease and cardiovascular autonomic control in rats with streptozotocin (STZ-induced DM. Male Wistar rats were divided into five groups. All groups were followed for 15 weeks. Trained control and trained diabetic rats underwent 10 weeks of exercise training, whereas previously trained diabetic rats underwent 14 weeks of exercise training. Renal function, proteinuria, renal sympathetic nerve activity (RSNA and the echocardiographic parameters autonomic modulation and baroreflex sensitivity (BRS were evaluated. In the previously trained group, the urinary albumin/creatinine ratio was reduced compared with the sedentary diabetic and trained diabetic groups (p<0.05. Additionally, RSNA was normalized in the trained diabetic and previously trained diabetic animals (p<0.05. The ejection fraction was increased in the previously trained diabetic animals compared with the diabetic and trained diabetic groups (p<0.05, and the myocardial performance index was improved in the previously trained diabetic group compared with the diabetic and trained diabetic groups (p<0.05. In addition, the previously trained rats had improved heart rate variability and BRS in the tachycardic response and bradycardic response in relation to the diabetic group (p<0.05. This study demonstrates that previous ET improves the functional damage that affects DM. Additionally, our findings suggest that the development of renal and cardiac dysfunction can be minimized by 4 weeks of ET before the induction of DM by STZ.

    To evaluate the safety and efficacy of the combination of interferon and cyclosporine for the treatment of hepatitis C in previous nonresponder patients. Preliminary data indicated that adding the immunosuppressive agent cyclosporin A to interferon might improve response rates in patients with hepatitis C. Ten previous virologic nonresponders with genotype 1 infection were included. Treatment consisted of interferon alfacon-1, 15 microg/d, and cyclosporine, 100 mg twice daily, for 4 weeks. The dose of interferon alfacon-1 was then decreased to 15 microg three times weekly, and cyclosporine was reduced to 50 mg twice daily. Therapy was continued for 48 weeks unless viremia persisted at week 24. Three of 10 subjects had an on-treatment virologic response, although one had a breakthrough with recurrent viremia during treatment and two relapsed after therapy was completed. On treatment responders had significantly higher trough cyclosporine levels at week 4 compared with nonresponders (P = 0.025). Serum creatinine levels remained stable, and no patient developed diabetes. Triglyceride levels increased during treatment. Cyclosporine was dose reduced in two patients for hypertension. Selected patients with hepatitis C tolerated therapy, including cyclosporine without severe or irreversible toxicity. Despite an association between higher cyclosporine levels and on-treatment response, the combination of cyclosporine and interferon was ineffective in producing a sustained response in previous nonresponder patients.

    Warm-up and stretching are suggested to increase hamstring flexibility and reduce the risk of injury. This study examined the short-term effects of warm-up, static stretching and dynamic stretching on hamstring flexibility in individuals with previous hamstring injury and uninjured controls. A randomised crossover study design, over 2 separate days. Hamstring flexibility was assessed using passive knee extension range of motion (PKE ROM). 18 previously injured individuals and 18 uninjured controls participated. On both days, four measurements of PKE ROM were recorded: (1) at baseline; (2) after warm-up; (3) after stretch (static or dynamic) and (4) after a 15-minute rest. Participants carried out both static and dynamic stretches, but on different days. Data were analysed using Anova. Across both groups, there was a significant main effect for time (p static stretching (p = 0.04) but significantly decreased after dynamic stretching (p = 0.013). The increased flexibility after warm-up and static stretching reduced significantly (p 0.05). Using ANCOVA to adjust for the non-significant (p = 0.141) baseline difference between groups, the previously injured group demonstrated a greater response to warm-up and static stretching, however this was not statistically significant (p = 0.05). Warm-up significantly increased hamstring flexibility. Static stretching also increased hamstring flexibility, whereas dynamic did not, in agreement with previous findings on uninjured controls. The effect of warm-up and static stretching on flexibility was greater in those with reduced flexibility post-injury, but this did not reach statistical significance. Further prospective research is required to validate the hypothesis that increased flexibility improves outcomes. ACTRN12608000638336.

    Regional cerebral blood flow (rCBF) and oxygen metabolism (rCMRO 2 ) were measured using the steady-state 15 O technique and positron emission tomography (PET) in six previously untreated patients with Parkinson's disease before and after trihexyphenidyl (THP) treatment. The patients comprised of 4 men and 2 women with Hoehn-Yahr stage II-III. Their ages at the onset of the study ranged from 46 to 57 years (mean±SD, 51.8±3.7) and the duration of the illness ranged from 10 to 48 months (mean±SD, 28.8±15.5). The PET study, assessments of the disability and cognitive function were undergone twice. The first time assessments were done was when the patients were not receiving any drugs, and the second time was one to three months after administration of 6 mg THP. All patients showed clinical improvement after THP treatment. The mean disability score of Unified Parkinson's Disease Rating Scale decreased from 35.1 (SD±11.3) to 25.7 (SD±11.6). The cognitive function assessed by Hasegawa's dementia rating scale-revised, Mini-Mental State Examination, Wechsler Adult Intelligence Scale-Revised, and Wechsler Memory Scale-Revised, were not significantly different before and after the THP treatment. After the THP treatment, rCBF and rCMRO 2 decreased significantly in the striatum (about 15%) and all cerebral cortices (about 10%) on both sides contralateral and ipsilateral to the predominantly symptomatic limbs. We conclude that an anticholinergic THP decreases the rCBF and rCMRO 2 significantly in the cerebral cortices without cognitive impairment in early untreated patients with Parkinson's disease.

  4. The NF-kB like factor DIF has weaker effects on Drosophila melanogaster immune defenses than previously thought.

    The Toll pathway of Drosophila melanogaster, when activated by the Beauveria bassiana fungus, directs the expression of the drosomycin and metchnikowin antimicrobial peptide genes by inducing the translocation into the nucleus of the DIF transcription factor. Accordingly, DIF mutants have been reported to have a lower resistance to fungi than control flies. However, as the longevity of non-infected DIF flies has not been measured in previous studies, it could be that survival times after infection are constrained by a low longevity. In the present study, DIF flies reared in conditions similar to those used in these previous studies had much lower survival time after infection than the control flies, but the longevity of non-infected DIF flies was also very low. Using rearing conditions controlling larval crowding, age of parents and mating status of experimental flies increased longevity of non-infected flies and survival time after infection in both strains. However, DIF flies had a similar survival time after infection as control ones or a slightly lower one, which shows that the effect of DIF is weaker than previously thought.

    Elective repeat caesarean delivery (ERCD) rates have been increasing worldwide, thus prompting obstetric discourse on the risks and benefits for the mother and infant. Yet, these increasing rates also have major economic implications for the health care system. Given the dearth of information on the cost-effectiveness related to mode of delivery, the aim of this paper was to perform an economic evaluation on the costs and short-term maternal health consequences associated with a trial of labour after one previous caesarean delivery compared with ERCD for low risk women in Ireland.

Participants carried out both static and dynamic stretches, but on different days. Data were analysed using Anova. RESULTS: Across both groups, there was a significant main effect for time (p < 0.001). PKE ROM significantly increased with warm-up (p < 0.001). From warm-up, PKE ROM further increased with static stretching (p = 0.04) but significantly decreased after dynamic stretching (p = 0.013). The increased flexibility after warm-up and static stretching reduced significantly (p < 0.001) after 15 minutes of rest, but remained significantly greater than at baseline (p < 0.001). Between groups, there was no main effect for group (p = 0.462), with no difference in mean PKE ROM values at any individual stage of the protocol (p > 0.05). Using ANCOVA to adjust for the non-significant (p = 0.141) baseline difference between groups, the previously injured group demonstrated a greater response to warm-up and static stretching, however this was not statistically significant (p = 0.05). CONCLUSION: Warm-up significantly increased hamstring flexibility. Static stretching also increased hamstring flexibility, whereas dynamic did not, in agreement with previous findings on uninjured controls.

Given the dearth of information on the cost-effectiveness related to mode of delivery, the aim of this paper was to perform an economic evaluation on the costs and short-term maternal health consequences associated with a trial of labour after one previous caesarean delivery compared with ERCD for low risk women in Ireland. METHODS: Using a decision analytic model, a cost-effectiveness analysis (CEA was performed where the measure of health gain was quality-adjusted life years (QALYs over a six-week time horizon. A review of international literature was conducted to derive representative estimates of adverse maternal health outcomes following a trial of labour after caesarean (TOLAC and ERCD. Delivery/procedure costs derived from primary data collection and combined both "bottom-up" and "top-down" costing estimations. RESULTS: Maternal morbidities emerged in twice as many cases in the TOLAC group than the ERCD group. However, a TOLAC was found to be the most-effective method of delivery because it was substantially less expensive than ERCD (€ 1,835.06 versus € 4,039.87 per women, respectively, and QALYs were modestly higher (0.84 versus 0.70. Our findings were supported by probabilistic sensitivity analysis. CONCLUSIONS: Clinicians need to be well informed of the benefits and risks of TOLAC among low risk women. Ideally, clinician-patient discourse would address differences in length of hospital stay and postpartum recovery time. While it is premature advocate a policy of TOLAC across maternity units, the results of the study prompt further analysis and repeat iterations, encouraging future studies to synthesis previous research and new and relevant evidence under a single

    Full Text Available The effect of different weekly feeding frequencies on Nile tilapia fingerlings of 2.02 g, was determined during 12 weeks. This was done by feeding the fish 7 days/week, 6 days/week or 5 days/week. After this restriction feeding period, all fish were fed as the control group (7 days/week during 26 days to study the capability of the fish to compensate the growth during this re-feeding period. At the end of the feeding restriction period, there were significant differences in weights among the different treatments, although the significance was detected only at 7 days/week level, which presented the highest final body weight compared with the other 2 treatments. The daily feed intake and the feed conversion and protein efficiency ratios did not present significant differences. Crude protein efficiency (CPE and gross energy efficiency (GEE were affected by the feeding frequency, presenting high values in fish fed 7 days/week. Growth results obtained during this re-feeding period indicate that weight gain (WG and specific growth rate (SGR presented a linear increase from 7 to 5 days/week, i.e. with increasing feed deprivation period the fish could compensate the growth effectively, trying to reach to the weight as those of the control group.

    Full Text Available Significant controversy still exists about ritonavir-boosted protease inhibitor monotherapy (mtPI/rtv as a simplification strategy that is used up to now to treat patients that have not experienced previous virological failure (VF while on protease inhibitor (PI -based regimens. We have evaluated the effectiveness of two mtPI/rtv regimens in an actual clinical practice setting, including patients that had experienced previous VF with PI-based regimens.This retrospective study analyzed 1060 HIV-infected patients with undetectable viremia that were switched to lopinavir/ritonavir or darunavir/ritonavir monotherapy. In cases in which the patient had previously experienced VF while on a PI-based regimen, the lack of major HIV protease resistance mutations to lopinavir or darunavir, respectively, was mandatory. The primary endpoint of this study was the percentage of participants with virological suppression after 96 weeks according to intention-to-treat analysis (non-complete/missing = failure.A total of 1060 patients were analyzed, including 205 with previous VF while on PI-based regimens, 90 of whom were on complex therapies due to extensive resistance. The rates of treatment effectiveness (intention-to-treat analysis and virological efficacy (on-treatment analysis at week 96 were 79.3% (CI95, 76.8-81.8 and 91.5% (CI95, 89.6-93.4, respectively. No relationships were found between VF and earlier VF while on PI-based regimens, the presence of major or minor protease resistance mutations, the previous time on viral suppression, CD4+ T-cell nadir, and HCV-coinfection. Genotypic resistance tests were available in 49 out of the 74 patients with VFs and only four patients presented new major protease resistance mutations.Switching to mtPI/rtv achieves sustained virological control in most patients, even in those with previous VF on PI-based regimens as long as no major resistance mutations are present for the administered drug.

    Human atrial natriuretic peptide (hANP) and spontaneous nitric oxide (NO) donor share cyclic guanosine monophosphate (cGMP) as a second messenger, but their effect on myocardium may differ. We compared the effect of hANP and sodium nitroprusside (SNP) on left ventricular (LV) mechano-energetics in heart failure (HF). Ten patients with HF due to previous myocardial infarction (LV ejection fraction: 45±3%) were instrumented with conductance and coronary sinus thermodilution catheters. LV contractility (Ees: slope of end-systolic pressure-volume relation) and the ratio of LV stroke work (SW) to myocardial oxygen consumption (SW/MVO2=mechanical efficiency) were measured in response to intravenous infusion of ANP (0.05 μg/kg/min) or SNP (0.3 μg/kg/min) to lower blood pressure by at least 10 mmHg, and changes in plasma cGMP. SNP had no effect on Ees, SW, or MVO2, thus SW/MVO2 remained unchanged (40.54±5.84% to 36.59±5.72%, p=0.25). ANP increased Ees, and decreased MVO2 with preserved SW, resulting in improved SW/MVO2 (40.49±6.35% to 50.30±7.96%, p=0.0073). Infusion of ANP (10.42-34.95 pmol/ml, p=0.0003) increased cGMP levels, whereas infusion of SNP had no effect (10.42-12.23 pmol/ml, p=0.75). Compared to SNP, the ANP-dependent increase in cGMP may ameliorate myocardial inotropy and energetics in HF. Copyright © 2015. Published by Elsevier Ltd.

    Cytogenetic evolution (CGE) in patients with myeloid neoplasms who relapsed after an allogeneic (allo) hematopoietic cell transplantation (HCT) has been evaluated by only few studies. The effect of the CGE on survival of relapsed allo-HCT recipients is not clear. The effect of previously received chemotherapy to induce CGE in this patient population has not been studied. The aims of our study are to (1) characterize the patterns of cytogenetic change in patients with myeloid neoplasms who relapsed after an allo-HCT, (2) evaluate the effect of CGE on survival, and (3) explore the association of CGE with previous chemotherapy (including the lines of salvage therapy, type of induction, and conditioning therapy). Of 49 patients with a myeloid malignancy (27 acute myeloid leukemia [AML], 19 myelodysplastic syndrome [MDS]/myeloproliferative neoplasm [MPN], and 3 chronic myelogenous leukemia) who relapsed after an allo-HCT, CGE was observed in 25 (51%), whereas 24 patients had unchanged cytogenetic findings at relapse. The CGE group carried more cytogenetic abnormalities at original diagnosis. The most frequent cytogenetic change was the acquisition of 3 or more new chromosomal abnormalities followed by acquisition of unbalanced abnormalities, aneuploidy, and emergence of apparently new clones unrelated to the original clone. The CGE cohort had higher proportion of MDS and MPN and fewer patients with de novo AML. Disease risk assessment category showed a trend to higher frequency of high-risk patients in the CGE group, though the difference was not statistically significant. Time from diagnosis to transplantation and time from transplantation to relapse were not different between the CGE and non-CGE groups. CGE and non-CGE cohorts had similar exposures to salvage therapy and to induction chemotherapy, as well as similar conditioning regimens; thus, no particular type of chemotherapy emerged as a predisposing factor to CGE. CGE was associated with significantly shortened

    Previous research suggests that parental divorce moderates genetic influences on body dissatisfaction. Specifically, the heritability of body dissatisfaction is higher in children of divorced versus intact families, suggesting possible gene-environment interaction effects. However, prior research is limited to a single, self-reported measure of body dissatisfaction. The primary aim of this study was to examine whether these findings extend to a different dimension of body dissatisfaction: body image perceptions. Participants were 1,534 female twins from the Minnesota Twin Family Study, aged 16-20 years. The Body Rating Scale (BRS) was used to assess body image perceptions. Although BRS scores were heritable in twins from divorced and intact families, the heritability estimates in the divorced group were not significantly greater than estimates in the intact group. However, there were differences in nonshared environmental effects, where the magnitude of these environmental influences was larger in the divorced as compared with the intact families. Different dimensions of body dissatisfaction (i.e., negative self-evaluation versus body image perceptions) may interact with environmental risk, such as parental divorce, in discrete ways. Future research should examine this possibility and explore differential gene-environment interactions using diverse measures. © 2015 Wiley Periodicals, Inc.

    Little is known of the importance of previous irradiation therapy for baseline characteristics and responsiveness to GH replacement in GH deficient (GHD) adults. In this prospective, single-centre, open-label study, the effects of 10-year GH replacement were determined in 18 GHD adults that had previously received conventional external fractionated pituitary irradiation therapy (IRR group) and 18 non-irradiated GHD patients (non-IRR group). All patients had adult onset disease and complete deficiency of anterior pituitary hormones and both groups were comparable in terms of age, gender, body mass index (BMI), and waist:hip ratio. At baseline, IRR patients had higher serum triglyceride (TG) and insulin levels and lower high density lipoprotein (HDL)-cholesterol (HDL-C) level than non-IRR patients (all pGH replacement improved body composition, bone mass and serum lipid profile without any between-group differences, except for a marginally more beneficial response in serum TG level in the IRR patients. After 10 years, there was no between-group difference in any variable after correction for a higher replacement dose of glucocorticoids in the IRR patients at study end using an analysis of covariance. During the 10-year GH replacement, 5 IRR patients suffered from vascular events (2 fatal) whereas only one non-fatal vascular event occurred in the non-IRR patients. IRR patients with GHD display a more severely impaired cardiovascular risk profile at baseline, which was reversed by the 10-year GH replacement after correction for the higher glucocorticoid dose at study end. However, vascular events occurred more frequently in the IRR patients. © 2013.

    The mechanisms linking ovarian hormones to negative affect are poorly characterized, but important clues may come from the examination of the brain's intrinsic organization. Here, we studied the effects of both the menstrual cycle and oral contraceptives (OCs) on amygdala and salience network resting-state functional connectivity using a double-blind, randomized, and placebo-controlled design. Hormone levels, depressive symptoms, and resting-state functional connectivity were measured in 35 healthy women (24.9±4.2 years) who had previously experienced OC-related negative affect. All participants were examined in the follicular phase of a baseline cycle and in the third week of the subsequent cycle during treatment with either a combined OC (30 μg ethinyl estradiol/0.15 mg levonorgestrel) or placebo. The latter time point targeted the midluteal phase in placebo users and steady-state ethinyl estradiol and levonorgestrel concentrations in OC users. Amygdala and salience network connectivity generally increased with both higher endogenous and synthetic hormone levels, although amygdala-parietal cortical connectivity decreased in OC users. When in the luteal phase, the naturally cycling placebo users demonstrated higher connectivity in both networks compared with the women receiving OCs. Our results support a causal link between the exogenous administration of synthetic hormones and amygdala and salience network connectivity. Furthermore, they suggest a similar, potentially stronger, association between the natural hormonal variations across the menstrual cycle and intrinsic network connectivity.

    Deboer, George E.

    To determine the effect of retesting on student learning in chemistry, three questions were addressed by means of a 3 × 2 (achievement level X treatment) factorial design: (1) Does retesting affect differently the end-of-semester mastery of course objectives of students who are grouped according to their previous achievement in science? (2) Do students who are given an opportunity to take retests merely delay their studying and perform at a lower level on initial tests than nonretested students? (3) Is the procrastination of retested students (if it exists) affected by their achievement level? The results showed that for one of four units low ability students who were retested demonstrated greater learning gains than low ability students who were not retested, and that procrastination, if it was present, did not have significant effects on student learning at any achievement level. Results were discussed in terms of the students' room for improvement, motivation to improve, and ability to improve.

    Regular follow-up is required in patients with previous intervention for coarctation of the aorta to detect recoarctation or aneurysm formation. In this study we describe the findings encountered on routine follow-up exams and we compare the use of contrast-enhanced 3D MR angiography (CE MRA) with fast spin-echo MRI (FSE) to study the thoracic aorta after previous intervention. In 51 consecutive patients previously treated for aortic coarctation, 74 MR studies of the thoracic aorta were performed during a 2-year period using CE MRA and FSE MRI. The thoracic aorta was evaluated for abnormalities of course, caliber, shape, and pathology of side branches. The CE MRA and FSE MRI studies were evaluated side by side by consensus of two reviewers evaluating which MR technique depicted the abnormalities of the thoracic aorta the best. Of 74 exams, six clinically important abnormalities were found: four aneurysms and two restenoses. Two small pseudoaneurysms were missed on the FSE studies. Contrast-enhanced MRA was judged to visualize aortic abnormalities better than FSE (47 of 74 MR studies) especially for the transverse aortic arch, coarctation site, left subclavian artery, and aortic arch configuration. For the ascending aorta and distal descending aorta, CE MRA and FSE performed equally well. Aortic diameters measured at four levels in the first 18 MRI studies showed no significant differences in diameter when measured by FSE or CE MRA (p = not significant). Clinically important abnormalities, such as aneurysm formation and restenosis, can be present years after treatment for aortic coarctation. In the regular follow-up of these patients, CE MRA may provide additional diagnostic information compared with FSE and should be included as part of the routine exam. (orig.)

    Recombinant human thyroid-stimulating hormone (rhTSH) enhances {sup 131}I uptake, permitting a decrease in radiation for the treatment of multinodular goiter (MNG). Our objective was to evaluate the safety and efficacy of a single 0.1-mg dose of rhTSH, followed by 30 mCi {sup 131}I, in patients with MNG. Seventeen patients (15 females, 59.0 {+-} 13.1 years), who had never been submitted to {sup 131}I therapy, received a single 0.1-mg injection of rhTSH followed by 30 mCi {sup 131}I on the next day. Mean basal thyroid volume measured by computed tomography was 106.1 {+-} 64.4 mL. {sup 131}I 24-h uptake, TSH, free-T4, T3, thyroglobulin, anti-thyroid antibodies, and thyroid volume were evaluated at regular intervals of 12 months. Mean {sup 131}I 24-h uptake increased from 18.1 {+-} 9.7 to 49.6 {+-} 13.4% (P < 0.001), a median 2.6-fold increase (1.2 to 9.2). Peak hormonal levels were 10.86 {+-} 5.44 mU/L for TSH (a median 15.5-fold increase), 1.80 {+-} 0.48 ng/dL for free-T4, 204.61 {+-} 58.37 ng/dL for T3, and a median of 557.0 ng/mL for thyroglobulin. The adverse effects observed were hyperthyroidism (17.6%), painful thyroiditis (29.4%) and hypothyroidism (52.9%). Thyroid volume was reduced by 34.3 {+-} 14.3% after 6 months (P < 0.001) and by 46.0 {+-} 14.6% after 1 year (P < 0.001). Treatment of MNG with a single 0.1-mg dose of rhTSH, followed by a fixed amount of radioactivity of {sup 131}I, leads to an efficacious decrease in thyroid volume for the majority of the patients, with a moderate incidence of non-serious and readily treatable adverse effects.

    Full Text Available We developed and validated a two-gene signature that predicts prognosis in previously-untreated chronic lymphocytic leukemia (CLL patients. Using a 65 sample training set, from a cohort of 131 patients, we identified the best clinical models to predict time-to-treatment (TTT and overall survival (OS. To identify individual genes or combinations in the training set with expression related to prognosis, we cross-validated univariate and multivariate models to predict TTT. We identified four gene sets (5, 6, 12, or 13 genes to construct multivariate prognostic models. By optimizing each gene set on the training set, we constructed 11 models to predict the time from diagnosis to treatment. Each model also predicted OS and added value to the best clinical models. To determine which contributed the most value when added to clinical variables, we applied the Akaike Information Criterion. Two genes were consistently retained in the models with clinical variables: SKI (v-SKI avian sarcoma viral oncogene homolog and SLAMF1 (signaling lymphocytic activation molecule family member 1; CD150. We optimized a two-gene model and validated it on an independent test set of 66 samples. This two-gene model predicted prognosis better on the test set than any of the known predictors, including ZAP70 and serum β2-microglobulin.

    Full Text Available Toxic epidermal necrolysis (TEN is a rare but life-threatening skin disease that is most commonly drug-induced. It has recently been suggested that Stevens-Johnson syndrome (SJS belongs to the same group of skin disorders, although it has a lower mortality rate than TEN. We report the case of a 26-year-old male schizophrenic patient with a history of carbamazepine-induced SJS 5 years earlier. At the time of his current admission, he was admitted to our psychiatry department with acute agitation due to schizophrenia. However, the patient and his family denied history of drug allergy. After 3 days of carbamazepine treatment, the patient developed TEN (body surface area > 90%. He was transferred to the burn center, but despite appropriate treatment, including intravenous hydrocortisone 200 mg q6h and being covered with sterile biological material, he died. It is important to note that re-administration of a drug that previously caused SJS may lead to TEN, which has a very high mortality rate.

    Aluminum titanate based ceramics are potential candidates for many industrial applications mainly due to their low coefficient of thermal expansion and high thermal shock resistance. However, these ceramics are susceptible to phase dissociation in temperature range between 1100 and 1300 deg C, with consequent deterioration of properties. In this paper, it was assessed the effect of previous formation of Al{sub 2}TiO{sub 5}, obtained by calcination and subsequent grinding of equimolar mixtures of Al{sub 2}O{sub 3} and TiO{sub 2}, containing MgO and SiO{sub 2}, additives which promote Al{sub 2}TiO{sub 5} stabilization. Compacted samples from calcinated and non-calcinated powders were evaluated considering densification, formed crystalline phases, as well as grains size and morphology, by means of dilatometer studies, sintering treatments, X-ray diffraction and scanning electron microscopy. The effect of previous formation of Al{sub 2}TiO{sub 5} was associated with the properties and obtained features. (author)

To evaluate current in-market perceptions of the aesthetic result and use of Voluma. Men and women >30 years who had received Restylane SubQ™ (Restylane) face, specifically in the malar and chin areas or both (mean 1.36 mL each to the right and left sides of the face). Seventy-five percent of injectors found Voluma fairly/very easy to inject and 84.5% found it easy to sculpt/massage. Most patients (98%) and physicians (98%) rated the aesthetic effect of Voluma as improved. Injectors rated Voluma as better than previous Restylane use in 69.1% of patients (P massage. Physicians and patients rated the cosmetic effects highly, and both groups reported a preference for Voluma in those patients previously treated with Restylane. © 2010 Wiley Periodicals, Inc.

    To investigate the potential beneficial effects of guideline-based pharmacological therapy on pulmonary function and quality of life (QOL) in Japanese chronic obstructive pulmonary disease (COPD) patients without prior treatment. Multicenter survey, open-label study of 49 Japanese COPD patients aged ≥ 40 years; outpatients with >10 pack years of smoking history; ratio of forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) patients. Significant changes over time were not observed for FEV1 and FVC, indicating lung function at initiation of treatment was maintained during the observation period. COPD assessment test scores showed statistical and clinical improvements. Cough, sputum, breathlessness, and shortness of breath were significantly improved. Lung function and QOL of untreated Japanese COPD patients improved and improvements were maintained by performing a therapeutic intervention that conformed to published guidelines.

    Placebos are typically defined as physiologically inactive substances that elicit a therapeutic response. The antipode of the placebo effect is the nocebo effect, or the negative effects of placebo, where unpleasant symptoms (e.g., adverse events) emerge after the administration of placebo. Placebo analgesia is one of the most striking examples of the cognitive modulation of pain perception. Herein we focus on the importance of placebo in headache research. We first review the mechanisms of the placebo effect. We then focus on the importance of placebo in the acute treatment of migraine. We follow by discussing the importance of placebo on the preventive treatment of migraine and our perspectives for the 5 years to come regarding the study of the placebos.

    Cancer sufferers are a subfertile group, and most treatments have the potential to adversely affect gonadal function. As cancer treatment becomes more effective and survival rates improve there are more cancer survivors in the reproductive age group for whom parenting is an important consideration. This article outlines the effects on fertility of cancer treatments and techniques to minimise the risk of infertility. The overall prospects for younger cancer sufferers to either retain their fertility or have genetic offspring is now better than ever before, due to advances in assisted reproductive technology, the appropriate use of fertility sparing surgery and other techniques to reduce the toxicity of therapy on the reproductive organs. These advances raise new moral and ethical concerns that must be considered before advising cancer sufferers of the options for preserving reproductive capacity.

    Full Text Available Objective: To identify the main causing factors of fear and anxiety of children previously to dental treatment. Methods: A descriptive and qualitative study held in the municipal district of Acaraú - CE with 10 children aged 4 to 6 years old, who did not present strong pain between August and September, 2006. At first, we applied the modified VPT (Venham Picture Test, an instrument containing a set of figures of children in different emotional states, which were presented to each child so that he pointed to what he considered to be further identified at the time. The second test, held before the consultation, consisted in asking to the children to free-hand draw the dental office, the dentist and auxiliary personnel asking to each child: what do you think about the dental office and the dentist? The drawings were submitted to idiographic analysis and categorized in units of significance for interpretation. Results: Three children on VPT and nine children on the drawings presented an increased level of anxiety. Causing factors such as the motor (high speed rotation, tooth extraction and white clothes could be found. Final considerations: By means of drawing we were able to efficiently obtain results in identifying some factors that cause fear and anxiety to the child patient. The modified VPT showed to be quick, easy to apply and acceptable to children, but sometimes was contradictory with the drawings.

    To determine the effect of B vitamin treatment on the incidence of cancer among patients with stroke or transient ischemic attack. A total of 8164 patients with recent stroke or transient ischemic attack were randomly allocated to double-blind treatment with 1 tablet daily of placebo or B vitamins (2 mg folic acid, 25 mg vitamin B(6), 500 μg vitamin B(12)) and followed for a median of 3.4 years for any cancer as an adverse event. There was no significant difference in the incidence of any cancer among participants assigned B vitamins compared with placebo (4.04% versus 4.59%; risk ratio, 0.86; 95% CI, 0.70-1.07) and no difference in cancer mortality (2.35% versus 2.09%; risk ratio, 1.09; 0.81-1.46). Among 1899 patients with diabetes, the incidence of cancer was higher among participants assigned B vitamins compared with placebo (5.35% versus 3.28%; adjusted risk ratio, 2.21; 1.31-3.73), whereas among 6168 patients without diabetes, the incidence of cancer was lower among participants assigned B vitamins compared with placebo (3.66% versus 5.03%; adjusted risk ratio, 0.67; 0.51-0.87; P for interaction=0.0001). Daily administration of folic acid, vitamin B(6), and vitamin B(12) to 8164 patients with recent stroke or transient ischemic attack for a median of 3.4 years had no significant effect, compared with placebo, on cancer incidence or mortality. However, a post hoc subgroup analysis raises the hypothesis that folic acid treatment may increase the incidence of cancer among diabetics and reduce the incidence of cancer among nondiabetics with a history of stroke or transient ischemic attack.

    Triptans are a recommended first-line treatment for moderate to severe migraine. Using clinical trial data, we evaluated the safety and tolerability of frovatriptan as acute treatment (AT) and as short-term preventive (STP) therapy for menstrual migraine (MM). Data from 2 Phase III AT trials (AT1: randomized, placebo controlled, 1 attack; AT2: 12-months, noncomparative, open label) and 3 Phase IIIb STP trials in MM (MMP1 and MMP2: randomized, placebo controlled, double blind, 3 perimenstrual periods; MMP3: open label, noncomparative, 12 perimenstrual periods) were analyzed. In AT1, patients treated each attack with frovatriptan 2.5 mg, sumatriptan 100 mg, or placebo. In AT2, they used frovatriptan 2.5 mg. In MMP1 and MMP2, women administered frovatriptan 2.5 mg for 6 days during the perimenstrual period, taking a loading dose of 2 or 4 tablets on day 1, followed by once-daily or BID frovatriptan 2.5 mg, respectively; in MMP3, they used BID frovatriptan 2.5 mg. In AT1, which was previously published in part, group differences in adverse events (AEs) were analyzed using the Fisher exact test, and response rates were compared using logistic regression. Post hoc analyses of sustained pain-free status with no AEs (SNAE) and sustained pain response with no AEs (SPRNAE) were performed using a 2-sample test for equality of proportions without continuity correction. For AT2 and the STP studies, data were summarized using descriptive statistics. Results of individual safety analyses for the STP studies were previously reported; the present report includes new results from a pooled analysis of MMP1 and MMP2 and a new analysis of MMP3 in which AEs were coded using Medical Dictionary for Regulatory Activities version 8.0. AT1 included 1206 patients in the safety group; AT2 included 496. In the STP studies, safety data were collected for 1487 women. In AT1 and AT2, 85.6% and 88.3%, respectively, of enrolled patients were women. Overall, AEs were generally mild to moderate (AT

    Practice guidelines have been developed for early-stage and locally advanced non-small cell lung cancer (NSCLC). However, many common clinical scenarios still require individualized decision making. This is true for locoregional relapse after initial stereotactic radiotherapy (stereotactic body radiation therapy or stereotactic ablative radiotherapy; SBRT or SABR), an increasingly utilized curative treatment option for stage I NSCLC. A consortium of expert radiation oncologists was established with the aim of providing treatment recommendations. In this scenario, a case was distributed to six radiation oncologists who provided their institutions' treatment recommendations. In this case, a patient developed local and mediastinal relapse after SABR (45 Gy, 3 fractions), comparable to the tumor burden in de novo stage IIIA NSCLC. Treatment recommendations were tabulated and a consensus conclusion was developed. Three institutions recommended evaluation for surgery. If the patient was not a surgical candidate, and/or refused surgery, definitive chemoradiation was recommended, including retreating the primary to full dose. European participants were more in favor of a non-surgical approach. None of the participants were reluctant to prescribe reirradiation, but two institutions prescribed doses lower than 60 Gy. Platinum-based doublets together with intensity-modulated radiotherapy were preferred. The institutional recommendations reflect the questions and uncertainties discussed in current stage III guidelines. All institutions agreed that previous SABR is not a contraindication for salvage chemoradiation. In the absence of high-quality prospective trials for recurrent NSCLC, all treatment options recommended in current guidelines for stage III disease can be considered in clinical scenarios such as this.

    Full Text Available Under conditions of Organic Farming, we investigated whether direct seeding of faba bean (Vicia faba L. into straw mulch from residues of precrop oats used for weed control enables at least occasional/opportunistic direct seeding in Organic Agriculture. Eight field trials were carried out at different study sites in North Rhine-Westphalia, Germany, in 2008-2009 and 2009-2010. Direct seeding (DS was performed into mulch layers of 0,4 and 6 t ha-1 of straw residues applied to the remaining stubble, simulating different yield levels of the precrop oats. LBS was used as a reference treatment, where straw was harvested, stubble tillage performed and seedbed prepared in fall and oil radish (Raphanus sativus grown as winter cover crop. Mouldboard ploughing combined with conventional seedbed preparation was performed in early spring to V. faba. Compared with LBS, straw mulch with subsequent direct seeding suppressed especially dicotyledonous annuals significantly. DS treatments with straw reduced the abundance of this group by 81 and 85% compared with LBS. Straw mulch resulted in effective suppression of photosensitive weeds such as Matricaria spp. and late germinating Chenopodium album. Grasses and perennial species occurred independent of the amount of straw. Compared with DS, the abundance of these weeds was reduced by 64 and 82% in LBS treatment. The shoot dry matter production of faba bean was retarded by DS compared with LBS, but significant yield losses could be avoided with straw residues of at least 4 t ha-1. Sufficient amount of straw of from the previous crop is a key criterion to facilitate organic no-till farming of faba bean in a suitable crop sequence when pressure of perennials and grasses is low.

    Preclinical studies have found radiotherapy enhances antitumour immune responses. We aimed to assess disease control and pulmonary toxicity in patients who previously received radiotherapy for non-small-cell lung cancer (NSCLC) before receiving pembrolizumab. We assessed patients with advanced NSCLC treated on the phase 1 KEYNOTE-001 trial at a single institution (University of California, Los Angeles, CA, USA). Patients were aged 18 years or older, had an Eastern Cooperative Oncology Group performance status of 1 or less, had adequate organ function, and no history of pneumonitis. Patients received pembrolizumab at a dose of either 2 mg/kg of bodyweight or 10 mg/kg every 3 weeks, or 10 mg/kg every 2 weeks, until disease progression, unacceptable toxicity, or other protocol-defined reasons for discontinuation. Disease response and pulmonary toxicity were prospectively assessed by Immune-related Response Criteria and Common Terminology Criteria for Adverse Events version 4.0. The primary objective of the KEYNOTE-001 trial was to assess the safety, side-effect profile, and antitumour activity of pembrolizumab. For our secondary analysis, patients were divided into subgroups to compare patients who previously received radiotherapy with patients who had not. Our primary objective was to determine whether previous radiotherapy affected progression-free survival, overall survival, and pulmonary toxicity in the intention-to-treat population. The KEYNOTE-001 trial was registered with ClinicalTrials.gov, number NCT01295827. Between May 22, 2012, and July 11, 2014, 98 patients were enrolled and received their first cycle of pembrolizumab. One patient was lost to follow-up. 42 (43%) of 97 patients had previously received any radiotherapy for the treatment of NSCLC before the first cycle of pembrolizumab. 38 (39%) of 97 patients received extracranial radiotherapy and 24 (25%) of 97 patients received thoracic radiotherapy. Median follow-up for surviving patients was 32·5

    Conclusion: No significant differences were observed in infertile women of advanced age, which may be due to the low GH dose. The GH adjuvant therapy for patients with one or more previous IVF treatment failures and for poor responders significantly improved the oocyte and embryo numbers as well as implantation and pregnancy rates.

    Primary Care is the fundamental axis of our health system and obliges us to be consistent with our prescriptions. The non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with increased cardiovascular risk and increased risk of all causes of death, as well as acute myocardial infarction (AMI) in patients with a previous myocardial infarction. Pain and cardiac patient management are 2 basic pillars in our daily activity, and we must know the limitations of NSAIDs in patients with established cardiovascular risk. We present a review of the scientific literature with primary interest in the role of NSAIDs and cardiovascular risk. The objective is to determine the relationship between the consumption of different NSAIDs and the fatal and non-fatal events among patients with known coronary disease. This is a review of the scientific literature with primary interest in the role of NSAIDs and cardiovascular risk. The literature review was conducted in PubMed search engines like Tripdatabase and with certain keywords. Of the 15 original papers found, 9 did not correspond completely to the central focus, so the approach was decided from 6 original articles from the past 5 years, which address the central focus of increased cardiovascular risk found (fatal and non-fatal events) in patients with prior cardiovascular disease or AMI being prescribed NSAIDs for any reason. The risk of fatal/non-fatal events in each of the studies is expressed by the odds ratio (OR)/hazard ratio (HR), defined as the probability of an event occurring. A moderate risk was observed for ibuprofen. It increases the risk of acute coronary syndrome after 5 years of cardiovascular event, especially in the 2nd year (OR 1.63; 95% CI 1.42-1.87). It also increases the risk of stroke (HR 1.23; 95% IC 1.10-1.38). Cyclo-oxygenase-2 inhibitors were the third risk group, after nabumetone and diclofenac. Celecoxib increases risk from the 14th day of treatment (HR 2.3; 95% CI 1.79-3.02), having an OR

    Continuing with the domestic 'Burnable Absorbers Research Plan' studies were done to estimate self-shielding effects during Gd 2 O 3 burnup as burnable absorber included in fuel pins of a CAREM geometry. In this way, its burnup was calculated without and with self-shielding. For the second case, were obtained values depending on internal pin radius and the effective one for the homogenized pin. For Gd 157, the burnup corresponding to the first case resulted 52.6 % and of 1.23 % for the effective one. That shows the magnitude of the effects under study. Considering that is necessary to perform one experimental verification, also are presented calculational results for the case to irradiate a pellet containing UO 2 (natural) and 8 wt % of Gd 2 O 3 , as a function of cooling time, that include: measurable isotopes concentrations, expected activities, and photon spectra for conditions able to be compared with bidimensional calculations with self-shielding. The irradiation time was supposed 30 dpp using RA-3 reactor at 10 MW. (author)

    We aimed to analyze the difference in 24-h blood pressure values during Ramadan of fasting and nonfasting individuals with no previous history of hypertension. This study was planned as a multicenter research study in the cities of Izmit, Zonguldak, Sivas, and Adana. The percentage changes in the blood pressure of the patients were calculated from their blood pressure measurements at 0 h while they were resting. A Food Frequency Questionnaire was filled out by all participants. Forty patients were included in the fasting group and 55 patients were included in the nonfasting group in the study. There was a difference between the two groups in percent changes of systolic measurements performed at the 4th (5% difference and P=0.020), 13th (6% difference and P=0.015), 14th (10% difference and P=0.017), 18th (9% difference and P=0.027), 19th (9% difference and P=0.020), and 20th (6% difference and P=0.014) hours with respect to the baseline measurement at the 0 h. There was a difference between the fasting and nonfasting groups in the Fasting Food Questionnaire results. Meat consumption was significantly higher in the fasting group. A systolic blood pressure increase in fasting patients was observed in measurements at 18:00, 19:00, and 20:00 h. We believe that an increase of more than 10% in blood pressure at the time of iftar is an important result of our study in terms of the meal preferences of the individuals under risk.

    Is pretreatment with misoprostol useful in insertion of intrauterine contraceptives (IUCs) after insertion failure at the first attempt? Pretreatment with intravaginal administration of 200 mcg of misoprostol after IUC insertion failure 10 and 4 h before the second attempt of IUC placement was significantly better than placebo at facilitating the insertion of an IUC. One of the reasons for low use of IUCs is the concept that insertion is difficult. Misoprostol was used in several randomized clinical trials (RCT) before IUC insertion to facilitate the insertion. In general, the results showed no significant differences when compared with placebo. However, most previous studies have been carried out among unselected women whereas the present study is among women with previous insertion failure. This was a double blind RCT conducted between February 2013 and October 2014. Participants were 104 women who requested an insertion of an IUC and the insertion failed at the first attempt. After insertion failure, the women received a sealed envelope with misoprostol or placebo. The randomization system (1: 1) in one block size was computer-generated. The study was conducted at a tertiary care centre. The women were instructed to insert vaginally one tablet of misoprostol 200 µg (Prostokos, Hebron, Cariacica, PE, Brazil) or placebo 10 and 4 h before the woman returned to the clinic for a new insertion attempt. The outcomes were successful IUC insertion and the use of a cervical dilator immediately prior to the insertion procedure. A total of 2639 women requested the insertion of an IUC during the study period. The IUC was inserted at the first attempt in 2535 women (96%) and 104 women in whom we were unable to insert the device were eligible to participate in the RCT. Four women declined and 100 women were randomized (55 for the misoprostol group and 45 for the placebo group). From the 100 participating women, the levonorgestrel-releasing intrauterine system (LNG-IUS) was

    Full Text Available The effectiveness of written corrective feedback (WCF in the improvement of language learners' grammatical accuracy has been a topic of interest in SLA studies for the past couple of decades. The present study reports the findings of a three-month study investigating the effect of direct unfocused WCF on the grammatical accuracy of elementary students in an EFL context. The researchers selected two intact classes totaling 33 students, and assigned each to a direct feedback group (n = 16 and a control group (n = 17. The students produced eight pieces of writing (a pretest, three writing tasks along with their revisions, and a posttest from which their grammatical accuracy was obtained. The results indicated that while the experimental group significantly outperformed the control group in the revision of the three writing tasks, no significant difference was found when the two groups produced a new piece of writing after a one-month interval. The study concludes that accuracy improvement caused by unfocused WCF during the revision process does not extend to EFL learners' future writing when no feedback is available, at least at the elementary level.

    Full Text Available Abstract Background Mycoplasma hyopneumoniae is the primary cause of enzootic pneumonia in pigs. Although vaccination is an important control tool, the results observed under field conditions are variable. This may be due to antigenic differences between the strains circulating in pig herds and the vaccine strain. This study compared the protective efficacy of four bacterins against challenge infection with a highly virulent field strain of M. hyopneumoniae. Seventy eight, one-week old piglets were randomly assigned to five treatment groups (A, B, C, D, E, 14 piglets each, and a negative control group (F consisting of 8 piglets.

    Persons who stutter (PWS) should be referred to the most effective treatments available, locally or regionally. A prospective comparison of the effects of the most common stuttering treatments in Germany is not available. Therefore, a retrospective evaluation by clients of stuttering treatments was carried out. The five most common German stuttering treatments (231 single treatment cases) were rated as to their perceived effectiveness, using a structured questionnaire, by 88 PWS recruited through various sources. The participants had received between 1 and 7 treatments for stuttering. Two stuttering treatments (stuttering modification, fluency shaping) showed favorable and three treatments (breathing therapy, hypnosis, unspecified logopedic treatment) showed unsatisfactory effectiveness ratings. The effectiveness ratings of stuttering modification and fluency shaping did not differ significantly. The three other treatments were equally ineffective. The differences between the effective and ineffective treatments were of large effect sizes. The typical therapy biography begins in childhood with an unspecified logopedic treatment administered extensively in single and individual sessions. Available comparisons showed intensive or interval treatments to be superior to extensive treatments, and group treatments to be superior to single client treatments. The stuttering treatment most often prescribed in Germany, namely a weekly session of individual treatment by a speech-language pathologist, usually with an assorted package of mostly unknown components, is of limited effectiveness. Better effectiveness can be expected from fluency shaping or stuttering modification approaches, preferably with an intensive time schedule and with group sessions. Readers will be able to: (a) discuss the five most prevalent stuttering treatments in Germany; (b) summarize the effectiveness of these treatments; and (c) describe structural treatment components that seem to be preferable

    This open-label, prospective, observational, Post-Marketing Surveillance (PMS) study assessed the efficacy and safety of donepezil in patients who had been switched from therapies currently used in Germany to treat Alzheimer's disease (AD), such as memantine and nootropics, due to insufficient efficacy or poor tolerability. A treatment-naive population was included as a comparator. Patients with AD were treated with donepezil and observed for a period of approximately 3 months. A cognitive assessment was made using the Mini-Mental State Examination (MMSE). Quality of life (QoL) was assessed by the investigators who answered the question 'How did therapy with donepezil influence the QoL of the patient and/or his family over the observation period?' and was graded using three ratings: improved/unchanged/worsened. Adverse events (AEs) were also monitored. A total of 913 patients entered the study (mean +/- SD MMSE score 18.03 +/- 5.34). Efficacy assessments were analyzed for three groups: an overall group of patients who had received any form of prior AD drug therapy (N+ group; n = 709); a subgroup of patients from the N+ group who had received prior memantine therapy only (M+ group; n = 111) and patients who were drug treatment naive (N- group; n = 204). In the evaluable population donepezil improved MMSE scores by 2.21 +/- 3.47 points on average, with similar improvements observed in all three groups. QoL was judged to be improved in at least 70% of patients, again with similar results obtained for all three groups. Donepezil was well tolerated, with 85 of 913 (9.3%) patients reporting AEs. The most common AEs were those typically seen with cholinergic therapies (i.e., diarrhoea, vomiting and nausea). In this observational PMS study, donepezil was shown to be efficacious and well tolerated in patients who were being insufficiently treated with memantine or nootropic therapy. The magnitude of response was similar to that observed in patients who were previously

    Substantial burden of diabetes and hypertension is on rise in India, leading to a twin epidemic. India, being a rural country, has unique problems regarding the treatment compliance which is a serious risk for morbidity and mortality. To assess the compliance to treatment of hypertension and diabetes amongst the diagnosed patients from rural area and to study reasons of non-compliance and knowledge and attitude. Community based, cross sectional, observational study conducted in the rural communities of Tara and Barapada villages of Raigad district of Maharashtra. Survey was conducted covering population of 2115 across 360 families, 250 at Barapada and 110 at Tara. All the cases of diabetes and hypertension diagnosed for more than one year were included. A structured and pre-tested questionnaire was administered including details on demography, medical documentation, treatment details and factors assessing the compliance, knowledge and attitude towards the diseases. When reviewed the treatment adherence pattern based on documentary evidence and interview of the patient, on history of taking medication strictly since the detection illness, it was found that more than 70% of the Diabetics and more than 75% of the Hypertensive have discontinued the treatment in between. The most common reasons of non-compliance is the lack of sufficient motivation for treatment adherence as many mentioned (61.4% diabetics, 55.8% hypertensives) difficulty to remember to take daily medication due to work or forgetfulness. This is followed by lack of money (50%diabetics, 55.8% hypertensives) and living far away from doctor in city (43% diabetics and 46% hypertensives). The study findings are only tip of iceberg and the non-adherence to the treatment of diabetes and hypertension in rural population is at alarmingly high. Illiteracy, lack of faith in treatment and motivation, unawareness and self-neglect as well as financial constraints and lack of specialist care in rural area is playing

    The efficacy and safety of biologic treatments have been established in patients with moderate to severe psoriasis, but there are few reports on biologic therapy for patients with psoriasis complicated by end-stage renal failure on hemodialysis (HD). In this report, we demonstrated the efficacy and safety of adalimumab for patients with severe psoriasis on HD. A 46-year-old Japanese man with a 14-year history of psoriasis was referred to our clinic in September 2009. He had developed hypertension and renal failure during a 7-year history of cyclosporin treatment. With the infliximab treatment, he achieved 75% improvement of the Psoriasis Area and Severity Index (PASI) score within 3 months from the PASI of 42.3 before the treatment. However, his renal failure gradually deteriorated, and HD was initiated at 1 year after the introduction of infliximab. Because of hydration during the i.v. injection of infliximab, he developed pulmonary edema with every infliximab treatment after starting HD. We switched to ustekinumab treatment, but his psoriasis was not improved. Then, we switched to adalimumab and achieved a PASI-100 response within 2 months. The patient received adalimumab treatment for more than a year without any adverse effects. In addition to our case, five articles reported cases of psoriasis patients with renal failure on HD who were treated with biologics. The psoriatic lesions were improved by biologics in these cases, and no severe adverse effects on the renal function were reported. Thus, biologics are a reasonable treatment option for patients with severe psoriasis with renal failure on HD. © 2015 Japanese Dermatological Association.

    In this study, wastewater from the output of three different secondary treatment facilities (Activated Sludge, Moving Bed Bioreactor and Coagulation-Flocculation) present in the municipal wastewater treatment plant of Vidy, Lausanne (Switzerland), was further treated with various oxidation processes (UV, UV/H2O2, solar irradiation, Fenton, solar photo-Fenton), at laboratory scale. For this assessment, 6 organic micropollutants in agreement with the new environmental legislation requirements in Switzerland were selected (Carbamazepine, Clarithromycin, Diclofenac, Metoprolol, Benzotriazole, Mecoprop) and monitored throughout the treatment. Also, the overall removal of the organic load was assessed. After each secondary treatment, the efficiency of the AOPs increased in the following order: Coagulation-Flocculation municipal wastewater subjected to biological treatment followed by UV/H2O2 resulted in the highest elimination levels. Wastewater previously treated by physicochemical treatment demonstrated considerably inhibited micropollutant degradation rates. The degradation kinetics were determined, yielding: k (UV) < k (UV/H2O2) and k (Fenton) < k (solar irradiation) < k (photo-Fenton). Finally, the evolution of global pollution parameters (COD & TOC elimination) was followed and the degradation pathways for the effluent organic matter are discussed. Copyright © 2015 Elsevier Ltd.

    As breast cancer outcomes improve and more people with breast cancer survive longer following diagnosis, many survivors must deal with the effects of treatment. Some adverse effects last a short time and have little influence on breast cancer patients' quality of life, yet others can cause long-term complications and add to increased morbidity and mortality among survivors. This article reviews the adverse effects of breast cancer treatments and how they affect the health and quality of life of those receiving treatment. The article also explains how adverse effects can interrupt treatment and how physicians and survivors can manage adverse effects of breast cancer treatment.

    Purpose Patients with epilepsy have increased morbidity and mortality. We evaluated the risk of myocardial infarction (MI), stroke, and death associated with epilepsy and examined if this risk was modified by treatment with antiepileptic drugs (AEDs). Methods A cohort consisting of the Danish...... population was followed from January 1997 to December 2006. The risk of MI, stroke, cardiovascular death, and all-cause death associated with epilepsy was estimated by multivariable Cox proportional hazard models stratified for occurrence of previous stroke. AED use was determined at baseline, and risks...... associated with exposure to individual AEDs were examined in patients with epilepsy. Results In patients without previous stroke, AED-treated epilepsy was associated with an increased risk of MI (hazard ratio [HR], 1.09; 95%CI, 1.00-1.19), stroke (HR, 2.22; 95%CI, 2.09-2.36), cardiovascular death (HR, 1...

    Full Text Available Following the abdominal surgery, extensive adhesions often occur and they can cause difficulties during laparoscopic operations. However, previous laparotomy is not considered to be a contraindication for laparoscopy. The aim of this study is to present that an insertion of Veres needle in the region of umbilicus is a safe method for creating a pneumoperitoneum for laparoscopic operations after previous laparotomy. In the last three years, we have performed 144 laparoscopic operations in patients that previously underwent one or two laparotomies. Pathology of digestive system, genital organs, Cesarean Section or abdominal war injuries were the most common causes of previouslaparotomy. During those operations or during entering into abdominal cavity we have not experienced any complications, while in 7 patients we performed conversion to laparotomy following the diagnostic laparoscopy. In all patients an insertion of Veres needle and trocar insertion in the umbilical region was performed, namely a technique of closed laparoscopy. Not even in one patient adhesions in the region of umbilicus were found, and no abdominal organs were injured.

    The effects of forced molting on blood glucose, rectal temperature, plasma T4, T3 and minerals were studied in hens previously fed rations with different protein contents (14, 17 and 20% crude protein). Blood samples were obtained from brachial veins for blood glucose, T4 and T3 were measured by radioimmunoassay, and plasma minerals were determined by atomic absorption spectroscopy. Blood glucose and rectal temperature were reduced during fasting regardless of previous protein intake. Pre molting T4 plasma level was higher in laying hens fed higher protein ration, but feed deprivation reduced T 4 and T 3 concentrations irrespective of protein intake, except T 4 level for 14% crude protein fed birds that increased during fasting. The data obtained in this experiment suggest that previous protein intake does not interfere with the metabolic changes during forced molt. (author). 19 refs, 1 fig, 4 tabs

    Dysregulation of the hepatocyte growth factor (HGF)/MET pathway is associated with poor prognosis, more aggressive biological characteristics of the tumor, and shortened survival in patients with metastatic colorectal cancer (mCRC). Onartuzumab (MetMAb) is a recombinant humanized monovalent monoclonal antibody directed against MET. We present the treatment rationale and protocol for an ongoing randomized multicenter placebo-controlled phase II study designed to evaluate the efficacy and safety of MetMAb combined with bevacizumab and mFOLFOX-6 (5-fluoruracil, leucovorin, and oxaliplatin). Eligible patients with previously untreated mCRC are randomized 1:1 to either mFOLFOX-6 combined with bevacizumab and placebo followed by 5-fluorouracil/leucovorin plus bevacizumab and placebo or mFOLFOX6, bevacizumab plus MetMAb followed by 5 FU/LV, bevacizumab, and MetMAb. The primary end point of this study is progression-free survival (PFS) in the intent-to-treat (ITT) population. Secondary end points include overall survival (OS), objective response rate, and safety. Subanalyses will be performed to evaluate the effect of MET receptor expression on study primary and secondary end points. Correlative studies will be performed on tissue- and blood-derived biomarkers related to both HGF/MET signaling and other associated pathway markers. Copyright © 2013 Elsevier Inc.

    Varicella vaccine effectiveness (VE) during outbreaks has been reported to be 71-100% against any disease and >90% against moderate/severe disease even in day-care centers (DCCs) and schools with low vaccination rates. A recent report suggested an effectiveness rate of 44% during a DCC outbreak despite a high vaccination rate. To reassess vaccination coverage, VE and severity of disease among previously vaccinated children after exposure during DCC outbreaks in northern Israel, where vaccination rates are low. During January to June 2003, active surveillance for varicella among children in northern Israel revealed outbreaks in 8 DCCs with children 3-6 years of age. Data concerning symptoms of the disease and the age at vaccination (for previously vaccinated children) were obtained from parents and health care providers for children who contracted the disease. Analysis of VE was limited to children who were continuously enrolled in DCCs during the outbreaks. The overall vaccination rate was 37%. The incidences of natural varicella and breakthrough varicella (BV) were 79 of 153 [52%; 95% confidence interval (CI) 44-60%] and 37 of 89 (41.5%; 95% CI 31-52%), respectively. VE was 20% (95% CI 0-40%) against disease of any severity and 93.4% (95% CI 75-98%) against moderate/severe disease. Ninety-four percent and 14% of children with BV and natural varicella, respectively, had mild disease (P vaccinated >2 years before the outbreak. During varicella outbreaks in DCCs with low vaccine coverage, previous vaccination provided poor protection against chickenpox, mostly among children who had been vaccinated >2 years earlier, but the disease appeared to be much milder among children with BV than among nonvaccinated children.

    Lactation may protect women with previous gestational diabetes mellitus (GDM) from developing type 2 diabetes mellitus, but the results of existing studies are inconsistent, ranging from null to beneficial. We aimed to conduct a systematic review to gather available evidence. Databases MEDLINE, CINAHL, PubMed, and EMBASE were searched on December 15, 2015, without restriction of language or publication year. A manual search was also conducted. We included observational studies (cross-sectional, case-control, and cohort study) with information on lactation and type 2 diabetes mellitus incidence among women with previous GDM. We excluded case studies without control data. Data synthesis was conducted by random-effect meta-analysis. Fourteen reports of 9 studies were included. Overall risk of bias using RoBANS ranged from low to unclear. Longer lactation for more than 4 to 12 weeks postpartum had risk reduction of type 2 diabetes mellitus compared with shorter lactation (OR 0.77, 95% CI 0.01-55.86; OR 0.56, 95% CI 0.35-0.89; OR 0.22, 95% CI 0.13-0.36; type 2 diabetes mellitus evaluation time 2 y, 2-5 y, and >5 y, respectively). Exclusive lactation for more than 6 to 9 weeks postpartum also had lower risk of type 2 diabetes mellitus compared with exclusive formula (OR 0.42, 95% CI 0.22-0.81). The findings support the evidence that longer and exclusive lactation may be beneficial for type 2 diabetes mellitus prevention in women with previous GDM. However, the evidence relies only on observational studies. Therefore, further studies are required to address the true causal effect. © 2017 The Authors.

    OR: 0.6 (95% CI: 0.2-1.4)]. The difference between the mean pain score in the intracervical anesthesia group and the NSAID group was Intracervical anesthesia was compared with an oral medication in this study. Intracervical injection of a saline solution or even a dry needling as the placebo for a double-blind study could be a more adequate control; however, this approach was not a protocol approved by the institutional review board. Considering that the majority of the insertions were easy (>80% in both groups), the results may not be extrapolated to difficult insertions with moderate/severe pain where local anesthesia may have a role. The findings can be generalized to most insertions in nulliparous women or in those without a previous vaginal delivery. There is currently no evidence to recommend the routine use of prophylactic intracervical anesthesia prior to LNG-IUS insertion; there is no evidence that this treatment reduces insertion-related pain.

    Patients express high anxiety preoperatively, because of fears related to anesthesia and its implications. The purpose of this survey was to gain insight into these fears and to study whether they are affected by patients' sex, age, education, or previous experience of anesthesia. Questionnaires with fixed questions were distributed to consenting, consecutive surgical patients before the pre-anesthetic visit. The questionnaires included patients' demographics and questions related to their fears about anesthesia. Four-hundred questionnaires were collected and analyzed. Eighty-one percent of patients experience preoperative anxiety. The main sources of their anxiety were fear of postoperative pain (84 %), of not waking up after surgery (64.8 %), of being nauseous or vomiting (60.2 %), and of drains and needles (59.5 %). Patients are less concerned about being paralyzed because of anesthesia (33.5 %) or of revealing personal issues (18.8 %). Gender seems to affect patients fears, with women being more afraid (85.3 vs. 75.6 % of men, p = 0.014). The effects of patients' age, level of education, and previous experience of anesthesia are minor, except for individual questions. Sixty-three percent of our patients (mostly women 67.4 vs. 57.4 % of men, p = 0.039) talk about these fears with their relatives, although a vast majority of 95.5 % would prefer to talk with the anesthesiologist and be reassured by him. All patients, mostly women, express fears about anesthesia; this fear leads to preoperative anxiety. Slight differences are observed for some individual questions among patients of different sex, education level, and previous experience of anesthesia.

    Poor hamstring strength-endurance is a risk factor for hamstring injuries. This study investigated the effectiveness of the single-leg Roman hold and Nordic hamstring curl in improving hamstring strength-endurance. Twelve Gaelic footballers (mean ± standard deviation age, height and mass were 25.17 ± 3.46 years, 179.25 ± 5.88 cm, 85.75 ± 4.75 kilo) with a history of hamstring injury were randomized into 2 groups that performed 6 weeks of either Nordic hamstring curl, or single-leg Roman chair hold training. The single-leg hamstring bridge (SLHB) was measured pre- and post- intervention. The Roman chair group showed a very likely moderate magnitude improvement on SLHB performance for both legs (23.7% for the previously injured leg [90% confidence interval 9.6% to 39.6%] and 16.9% for the non-injured leg [6.2% to 28.8%]). The Nordic curl group showed a likely trivial change in SLHB performance for the non-injured leg (-2.1% [-6.7% to 2.6%]) and an unclear, but possibly trivial change for the previously injured leg (0.3% [-5.6% to 6.6%]). The Roman chair group improved very likely more with a moderate magnitude in both the non-injured (19.5% [8.0% to 32.2%]) and the previously injured leg (23.3% [8.5% to 40.0%]) compared to the Nordic curl group. This study demonstrated that 6-weeks single-leg Roman chair training substantially improved SLHB performance, suggesting that it may be an efficacious strategy to mitigate hamstring (re-) injury risk. Conversely, 6-weeks Nordic curl training did not substantially improve SLHB performance, suggesting this may not be the intervention of choice for modifying this risk factor.

    Full Text Available Background. Phase I of this study was aimed at comparing the profiles of oxidative stress biomarkers in patients with history of nonmelanoma skin cancer (NMSC, previously treated with surgery, to the healthy subjects. Phase II aimed to evaluate the effects of supplementary antioxidant therapy on the levels of biomarkers in the case group. Materials and Methods. In Phase I, oxidative stress biomarkers were measured in blood samples obtained from 24 healthy subjects and 60 patients with history of NMSC previously treated with surgery. In Phase II, the 60 patients with history of NMSC were randomized into two subgroups, one receiving placebo (n=34 and the other (n=26 receiving vitamin C, vitamin E, and zinc supplementation for 8 weeks, followed by reevaluation of biomarkers. Results. In Phase I, patients with history of NMSC showed increased plasma concentrations of all biomarkers, but only 15-F2t-isoprostane was significantly higher than in the healthy subjects. Risk of NMSC increased by 4% for each additional 1 pg/mL increase in 15-F2t-isoprostane. In Phase II, supplementation did not significantly reduce levels of oxidative stress biomarkers. Conclusion. Patients with history of NMSC had significantly high 15-F2t-isoprostane plasma levels; supplementation did not result in significant reduction of oxidative stress biomarkers. This trial was registered with ClinicalTrials.gov (ID NCT02248584.

    Since stressful situations are considered risk factors for the development of depression and there are few studies evaluating prevention therapies for this disease, in the present study we evaluated the effect of previous physical exercise in animals subjected to chronic variable stress (CVS), an animal model of depression, on behavior tasks. We also investigated some parameters of oxidative stress and Na + , K + -ATPase activity, immunocontent and gene expression of alpha subunits in amygdala and hippocampus of rats. Young male rats were randomized into four study groups (control, exercised, stressed, exercised+stressed). The animals were subjected to controlled exercise treadmill for 20min,three times a week, for two months prior to submission to the CVS (40days). Results show that CVS impaired performance in inhibitory avoidance at 24h and 7days after training session. CVS induced oxidative stress, increasing reactive species, lipoperoxidation and protein damage, and decreasing the activity of antioxidant enzymes. The activity of Na + , K + -ATPase was decreased, but the immunocontents and gene expression of catalytic subunits were not altered. The previous physical exercise was able to improve performance in inhibitory avoidance at 24h after training; additionally, exercise prevented oxidative damage, but was unable to reverse completely the changes observed on the enzymatic activities. Our findings suggest that physical exercise during the developmental period may protect against aversive memory impairment and brain oxidative damage caused by chronic stress exposure later in life.

    The aim of this study was to assess patient preference in terms of quality of life (QoL), analgesia and bowel function for patients with moderate to severe chronic non-malignant pain, when treated with oxycodone PR/naloxone PR compared with the previous WHO-step I and/or WHO-step II analgesic treatment . This was a 3-week open-label phase 3b study conducted in Belgium and the Netherlands, after 3 weeks patients could enter an extension phase. Patient preference with respect to QoL for oxycodone PR/naloxone PR treatment compared with previous WHO-step I and/or WHO-step II analgesics was assessed. A patient was considered a responder with respect to QoL if this assessment was 'better' or 'much better' compared with previous WHO-step I or II analgesics at any time point. Response rate with respect to QoL was 59.2% (95% CI: 51.7-66.8%) for the Full Analysis (FA)-population, for the Per Protocol-population response rate was 71.7% (95% CI: 63.1-80.3%). Explorative analysis showed that response rate with respect to QoL was highest in constipated patients pretreated with WHO-step II analgesics (73.8%). Mean ± SD pain score in the FA-population at start was 74.7 ± 16.6 decreasing to 53.9 ± 24.3 after a median (range) treatment period of 173.5 (31-771) days. For constipated subjects the significant reduction in constipation [improvement of the Bowel Function Index (BFI)], was -24.8 points (95% CI: -17.1 to -32.5). BFI for non-constipated subjects remained well below 28.8. Adverse events with oxycodone PR/naloxone PR treatment were well-known opioid-related adverse events. This study shows that the studied patients previously treated with WHO-step I and/or WHO-step II analgesics prefer treatment with oxycodone PR/naloxone PR with respect to QoL. Moreover, the study shows that treatment with oxycodone PR/naloxone PR significantly reduces OIC in constipated patients and that non-constipated patients do not develop OIC during treatment with oxycodone PR/naloxone PR.

    The effect of previous natural pandemic H1N1 (H1N1 pdm09) influenza infection on the immunogenicity to subsequent inactivated influenza vaccination in children has not been well studied. We aimed to evaluate the effect of H1N1 pdm09 natural infection and vaccination on the immunogenicity to subsequent 2010-2011 seasonal inactivated influenza vaccination in children. From October 2010 to May 2011, we conducted an open-label, multi-center study in children aged 6 months -18 years in Korea. We measured antibody titers with a hemagglutination-inhibition (HI) assay at baseline, 1 month, and 6 months after vaccination with trivalent split or subunit vaccines containing H1N1 pdm, A/H3N2, and B. The subjects were classified into 4 groups depending on the presence of laboratory-confirmed H1N1 pdm09 infection and/or vaccination in the 2009-2010 season; Group I: vaccination (-)/infection(-), Group II: vaccination (-)/infection(+), Group III: vaccination (+)/infection(-), Group IV: vaccination (+)/infection(+). Among the subjects in group I, 47 subjects who had a baseline titer >1:10 were considered to have an asymptomatic infection. They were included into the final group II (n = 80). We defined the new group II as the infection-primed (IP) group and group III as the vaccine-primed (VP) group. Seroconversion rate (57.5 % vs 35.9 %, p = 0.001), seroprotection rate at 6 months after vaccination (70.8 % vs 61.8 %, p = 0.032), and GMT at 1 month after vaccination (129.9 vs 66.5, p = 0.002) were significantly higher in the IP group than in the VP group. In the 9-18 year-old group, seroconversion rate and immunogenicity at 1 and 6 months were significantly higher in the IP group than in the VP group. However in the 1-7 year-old age group, there was no significant difference between the two groups. Previous H1N1 pdm09 infection appears to have positive effects on immunogenicity of subsequent inactivated influenza vaccines against H1N1 pdm09 in older

  14. Previous Crop and Cultivar Effects on Methane Emissions from Drill-Seeded, Delayed-Flood Rice Grown on a Clay Soil

    Directory of Open Access Journals (Sweden)

    Alden D. Smartt

    2016-01-01

    Full Text Available Due to anaerobic conditions that develop in soils under flooded-rice (Oryza sativa L. production, along with the global extent of rice production, it is estimated that rice cultivation is responsible for 11% of global anthropogenic methane (CH4 emissions. In order to adequately estimate CH4 emissions, it is important to include data representing the range of environmental, climatic, and cultural factors occurring in rice production, particularly from Arkansas, the leading rice-producing state in the US, and from clay soils. The objective of this study was to determine the effects of previous crop (i.e., rice or soybean (Glycine max L. and cultivar (i.e., Cheniere (pure-line, semidwarf, CLXL745 (hybrid, and Taggart (pure-line, standard-stature on CH4 fluxes and emissions from rice grown on a Sharkey clay (very-fine, smectitic, thermic Chromic Epiaquerts in eastern Arkansas. Rice following rice as a previous crop generally had greater (p<0.01 fluxes than rice following soybean, resulting in growing season emissions (p<0.01 of 19.6 and 7.0 kg CH4-C ha−1, respectively. The resulting emissions from CLXL745 (10.2 kg CH4-C ha−1 were less (p=0.03 than those from Cheniere or Taggart (15.5 and 14.2 kg CH4-C ha−1, resp., which did not differ. Results of this study indicate that common Arkansas practices, such as growing rice in rotation with soybean and planting hybrid cultivars, may result in reduced CH4 emissions relative to continuous rice rotations and pure-line cultivars, respectively.

    Purpose: To determine the safety and radiation-enhancing effect of sodium glycididazole in laryngeal squamous cell carcinoma (stage T3-4,N0-3,M0) with conventional radiotherapy. Patients and methods: Patients with locoregional advanced laryngeal cancer (stage T3-4,N0-3,M0) were included: group 1(control, n = 30)were not administered of sodium glycididazole; group 2 (test, n = 30) received sodium glycididazole at a dose of 700 mg/m2 intravenous infusion 30 minutes before radiotherapy three times a week. Surrogate end-points of efficacy were tumor and nodal size. Safety parameters were vomiting, nausea, mucositis, laryngeal edema, esophagus and skin reaction, dysphagia, dyspnea, neurological deficit. Patients were evaluated weekly during treatment for 7 weeks and thereafter monthly for 3 months. Results: In the test, the overall response rate was 88.89% (95% CI, 71.00-97.00%) at 7 weeks and 92.59% (95% CI, 76.00 to 99.00%) at 1 month of follow-up. In the control, the overall response rate was 62.5% (95% CI, 41.00 to 81.00%) at 7 weeks and 58.33% (95% CI, 37.00 to 78.00%) at 1 month of follow-up. The short-term locoregional response rate was better in the test group at 7 weeks (p = 0.027) and at 1 month (p = 0.005) of follow-up. The test group had significantly more nausea and vomiting in weeks 1 (p = 0.047), 2 (p = 0.007), and 3 (p = 0.01) of treatment. Conclusions: The study indicates sodium glycididazole is an effective radiation-enhancing agent that improves short-term locoregional control and is well tolerated in patients with loco regionally advanced laryngeal cancer.

    To assess how the quality of metronome-guided cardiopulmonary resuscitation (CPR) was affected by the chest compression rate familiarised by training before the performance and to determine a possible mechanism for any effect shown. Prospective crossover trial of a simulated, one-person, chest-compression-only CPR. Participants were recruited from a medical school and two paramedic schools of South Korea. 42 senior students of a medical school and two paramedic schools were enrolled but five dropped out due to physical restraints. Senior medical and paramedic students performed 1 min of metronome-guided CPR with chest compressions only at a speed of 120 compressions/min after training for chest compression with three different rates (100, 120 and 140 compressions/min).

    To evaluate the effect of continuous positive airway pressure (CPAP) on the nostrils of patients with sleep apnea-hypopnea syndrome and its impact on quality of life, and to identify predictive factors for compliance. Longitudinal prospective study. Thirty-six consecutive patients evaluated before and 2 months after CPAP using the following variables: clinical (eye, nose and throat [ENT] symptoms, Epworth test, anxiety/depression scales, general and rhinoconjunctivitis-specific quality of life); anatomical (ENT examination, computed tomography); functional (auditive and Eustachian tube function, nasal flow, mucociliary transport); biological (nasal cytology); and polisomnographics. The sample was divided into compliers (≥4h/d) and non-compliers (Nasal dryness (P=.000), increased neutrophils in nasal cytology (P=.000), and deteriorating ciliary function were evidenced, particularly in compliers. No significant differences were observed in the other variables. Baseline sleepiness was the only factor predictive of compliance. CPAP in patients without previous nasal pathology leads to an improvement in a series of clinical parameters and causes rhinitis and airway dryness. Some ENT variables worsened in compliers. Sleepiness was the only prognostic factor for poor tolerance. Copyright © 2016 SEPAR. Publicado por Elsevier España, S.L.U. All rights reserved.

    To assess the cost-effectiveness of ceritinib vs alternatives in patients who discontinue treatment with crizotinib in anaplastic lymphoma kinase-positive (ALK+) non-small cell lung cancer (NSCLC) from a Canadian public healthcare perspective. A partitioned survival model with three health states (stable, progressive, and death) was developed. Comparators were chosen based on reported utilization from a retrospective Canadian chart study; comparators were pemetrexed, best supportive care (BSC), and historical control (HC). HC comprised of all treatment alternatives reported. Progression-free survival and overall survival for ceritinib were estimated using data reported from single-arm clinical trials (ASCEND-1 [NCT01283516] and ASCEND-2 [NCT01685060]). Survival data for comparators were obtained from published clinical trials in a NSCLC population and from a Canadian retrospective chart study. Parametric models were used to extrapolate outcomes beyond the trial period. Drug acquisition, administration, resource use, and adverse event (AE) costs were obtained from databases. Utilities for health states and disutilities for AEs based on EQ-5D were derived from literature. Incremental costs per quality-adjusted life year (QALY) gained were estimated. Univariate and probabilistic sensitivity analyses were performed. Over 4 years, ceritinib was associated with 0.86 QALYs and total direct costs of $89,740 for the post-ALK population. The incremental cost-effectiveness ratio (ICER) was $149,117 comparing ceritinib vs BSC, $80,100 vs pemetrexed, and $104,436 vs HC. Additional scenarios included comparison to docetaxel with an ICER of $149,780 and using utility scores reported from PROFILE 1007, with a reported ICER ranging from $67,311 vs pemetrexed to $119,926 vs BSC. Due to limitations in clinical efficacy input, extensive sensitivity analyses were carried out whereby results remained consistent with the base-case findings.

    Full Text Available BACKGROUND: The SARS outbreak of 2002-2003 presented clinicians with a new, life-threatening disease for which they had no experience in treating and no research on the effectiveness of treatment options. The World Health Organization (WHO expert panel on SARS treatment requested a systematic review and comprehensive summary of treatments used for SARS-infected patients in order to guide future treatment and identify priorities for research. METHODS AND FINDINGS: In response to the WHO request we conducted a systematic review of the published literature on ribavirin, corticosteroids, lopinavir and ritonavir (LPV/r, type I interferon (IFN, intravenous immunoglobulin (IVIG, and SARS convalescent plasma from both in vitro studies and in SARS patients. We also searched for clinical trial evidence of treatment for acute respiratory distress syndrome. Sources of data were the literature databases MEDLINE, EMBASE, BIOSIS, and the Cochrane Central Register of Controlled Trials (CENTRAL up to February 2005. Data from publications were extracted and evidence within studies was classified using predefined criteria. In total, 54 SARS treatment studies, 15 in vitro studies, and three acute respiratory distress syndrome studies met our inclusion criteria. Within in vitro studies, ribavirin, lopinavir, and type I IFN showed inhibition of SARS-CoV in tissue culture. In SARS-infected patient reports on ribavirin, 26 studies were classified as inconclusive, and four showed possible harm. Seven studies of convalescent plasma or IVIG, three of IFN type I, and two of LPV/r were inconclusive. In 29 studies of steroid use, 25 were inconclusive and four were classified as causing possible harm. CONCLUSIONS: Despite an extensive literature reporting on SARS treatments, it was not possible to determine whether treatments benefited patients during the SARS outbreak. Some may have been harmful. Clinical trials should be designed to validate a standard protocol for dosage

    Nanoparticle albumin-bound (nab) paclitaxel is a promising new therapeutic agent for all histologic types of non-small-cell lung cancer (NSCLC). We recently performed a phase 2 study of weekly nab-paclitaxel in patients with previously treated advanced NSCLC, finding promising activity and acceptable toxicity for this regimen. We have now designed a randomized phase 3 intergroup study (J-AXEL, UMIN000017487) to examine the clinical benefit and safety of nab-paclitaxel compared to docetaxel in patients with previously treated advanced NSCLC. Patients are randomized to receive either docetaxel (60 mg/m 2 on day 1 every 3 weeks, control arm) or nab-paclitaxel (100 mg/m 2 on days 1, 8, and 15 every 3 weeks, experimental arm), with each drug being administered until disease progression or unacceptable toxicity. The study will evaluate the noninferiority of nab-paclitaxel relative to docetaxel for the primary end point of overall survival. If the primary objective is achieved, this study will provide evidence for a new alternative treatment option for patients with previously treated advanced NSCLC. Copyright © 2016 Elsevier Inc.

    We estimated the potential impact and cost-effectiveness of providing 3-doses of nonavalent human papillomavirus (HPV) vaccine (9vHPV) to females aged 13-18 years who had previously completed a series of quadrivalent HPV vaccine (4vHPV), a strategy we refer to as "additional 9vHPV vaccination." We used 2 distinct models: (1) the simplified model, which is among the most basic of the published dynamic HPV models, and (2) the US HPV-ADVISE model, a complex, stochastic, individual-based transmission-dynamic model. When assuming no 4vHPV cross-protection, the incremental cost per quality-adjusted life-year (QALY) gained by additional 9vHPV vaccination was $146 200 in the simplified model and $108 200 in the US HPV-ADVISE model ($191 800 when assuming 4vHPV cross-protection). In 1-way sensitivity analyses in the scenario of no 4vHPV cross-protection, the simplified model results ranged from $70 300 to $182 000, and the US HPV-ADVISE model results ranged from $97 600 to $118 900. The average cost per QALY gained by additional 9vHPV vaccination exceeded $100 000 in both models. However, the results varied considerably in sensitivity and uncertainty analyses. Additional 9vHPV vaccination is likely not as efficient as many other potential HPV vaccination strategies, such as increasing primary 9vHPV vaccine coverage.

  4. Effectiveness of psychopharmacology in Anorexia Nervosa treatment

    2015-06-01

    Full Text Available The eating disorder that generates the highest death rate is that of anorexia nervosa, and current treatment is a combination of equalization of somatic state and patient education. Moreover, psychical symptoms occurring in the course of anorexia nervosa are thought to have a crucial influence on the course of the disease. Hence, in medical literature, the effectiveness of psychotherapeutic interventions is also widely described. Still, the implementation of appropriate psychopharmacology is now considered an additional method of treatment, rather than a therapy of choice. Yet, in spite of many years of research, there are no absolute recommendations given, nor are instructions within the scope of psychopharmacological treatment proffered, although the selection of psychopharmacological items must respect both the patient’s psychic and somatic states. In recent years, the popularity of psychopharmacological treatment has increased; therefore, we feel that it is justified to present the latest scientific information in this respect.

    Children who experience early life toxic stress are at risk of long-term adverse health effects that may not manifest until adulthood. This article briefly summarizes the findings in recent studies on toxic stress and childhood adversity following the publication of the American Academy of Pediatrics (AAP) Policy Report on the effects of toxic stress. A review of toxic stress and its effects is described, including factors of vulnerability, resilience, and the relaxation response. An integrative approach to the prevention and treatment of toxic stress necessitates individual, community and national focus.

    Oxaliplatin + S-1 is a recognized treatment regimen in Japan, but there are no Japanese clinical data on an oxaliplatin dose of 130 mg/m 2 . The current research involves a single-arm, prospective, phase II clinical trial to examine the efficacy and safety of oxaliplatin + S-1 with an oxaliplatin dose of 130 mg/m 2 to treat HER2-negative advanced/recurrent gastric cancer previously untreated with chemotherapy in Japan. The primary endpoint of this trial will be the response rate, and the secondary endpoints will be the safety profile of oxaliplatin + S-1, progression-free survival, the response rate in subjects under the age of 75, overall survival, time to treatment failure, duration of treatment, time to failure of strategy, and dose intensity. The threshold response rate is 45% and the expected response rate is 60%. Assuming that a one-tailed score test will be performed with an α of 0.05, 68 patients are needed to ensure a statistical power of 80%. Planned enrollment is 70 subjects and the total duration of this trial is expected to be 3 years. Since replacing cisplatin with oxaliplatin should provide the same level of therapeutic efficacy while limiting adverse events and simplifying treatment, oxaliplatin + S-1 may be increasingly used to treat gastric cancer in Japan. Verifying the efficacy and safety of oxaliplatin + S-1 with an oxaliplatin dose of 130 mg is an important task that the current trial has set out to achieve. The protocol was registered at the website of the University Hospital Medical Information Network (UMIN), Japan (protocol ID UMIN000017550) on May 29, 2015.

    This phase I/II study was designed to determine the maximum tolerated dose of tivantinib in combination with standard dose FOLFOX for the treatment of patients with advanced solid tumors and to evaluate the safety and efficacy of this combination for patients with previously untreated metastatic adenocarcinoma of the distal esophagus, gastroesophageal (GE) junction, or stomach. Patients with advanced solid tumors for which FOLFOX would be appropriate chemotherapy received escalating doses of tivantinib BID (days 1-14) in a standard 3 + 3 design in phase I. In phase II, patients with advanced GE cancer received standard FOLFOX day 1 and tivantinib (360 mg PO BID) days 1-14 of each 2-week cycle. Restaging occurred every four cycles. The primary phase II endpoint was response rate (RR). Forty-nine patients were enrolled (15 on phase I and 34 on phase II). The expansion dose was established as tivantinib 360 mg BID in combination with FOLFOX. Thirty-two phase II patients were treated for a median of eight cycles (range, 1-38), with an overall RR of 38%. Treatment-related toxicities included neutropenia, fatigue, diarrhea, nausea, and peripheral neuropathy. Median progression-free survival (PFS) was 6.1 hmonths with a median time to progression of 7.0 months. Median overall survival was 9.6 months. Two patients remain on study at the time of this analysis. The combination treatment of tivantinib plus FOLFOX in patients with advanced GE cancer showed a response and PFS in the range of historical controls for first-line FOLFOX therapy. However, two patients had extended time on study treatment (36 and 45 cycles) at the time of data cutoff.

    The effect of exogenous human biosynthetic growth hormone (HGH; 12 IU/day; Norditropin, Novo-Nordisk) on the response to ovarian stimulation using a buserelin/human menopausal gonadotrophin (HMG) regimen was assessed in women who had previously shown a 'poor response' in spite of increasing doses of HMG. Forty patients were recruited into a prospective double-blind placebo-controlled study. The serum follicle stimulating hormone (FSH) on day 2-5 of a menstrual cycle (HGH compared to the placebo cycle resulted in increased serum concentrations of fasting insulin on the 8th (median 3.9 versus 5.8 mU/l; P HGH. After 8 days of co-treatment with HGH the number of cohort follicles (14-16.9 mm) was significantly increased, but this change was not sustained on the day of HCG administration. No statistical difference in the serum oestradiol on the 8th day of HMG or day of HCG, length of the follicular phase, total dose of HMG used, or the number of oocytes collected was seen between the placebo or HGH cycles. This study demonstrates that HGH does not improve the ovarian response to ovulation induction in previous poor responders.

    [Purpose] To present the outcome of a patient, having sciatica and MRI-verified disc herniation/sequestration who underwent Chiropractic BioPhysics ® (CBP ® ) protocol designed to improve the lumbar lordosis. [Subject and Methods] A 56-year-old male suffered from chronic low back pain and recent sciatica due to lumbar disc herniation despite being under continuous care from three previous chiropractors. Radiographic analysis revealed a lumbar hypolordosis and MRI confirmed disc herniation and sequestration at L4-L5. Generalized decreased lumbar range of motion and multiple positive orthopedic and neurologic tests were present. [Results] After 26 treatments of CBP lumbar extension traction over 9-weeks a total reduction of the disc herniation and sequestration occurred with concomitant improvement in neurologic symptoms. Continuing maintenance treatments, an 8 year follow-up shows no relapse of condition and patient remained in good health. [Conclusion] A patient with lumbar disc herniation/sequestration was successfully treated with CBP technique procedures including lumbar extension traction that achieved a significant healing of herniation and significant reduction in symptoms not obtained following traditional chiropractic procedures alone. The quick reduction in lumbar disc herniation would appear to be related to a segmental disc unloading force produced during extension traction procedures for increasing the lumbar curvature.

  15. Psoriasis: characteristics, psychosocial effects and treatment options.

    LENUS (Irish Health Repository)

    2012-02-01

    Psoriasis is a complex chronic non-infectious inflammatory skin disease with a variety of different presentations. The classic presentation is of well-defined red plaques with silver scale. The characteristic scale makes the disorder highly visible and intrusive on the patient\\'s lifestyle. The visible nature of the disease ensures that psoriasis has both physical and psychosocial effects. In normal skin, epidermal cell reproduction and proliferation takes 28 days. In psoriasis this process is considerably accelerated to approximately 4 days, resulting in the deposit of immature cells on the skin. While the exact cause of this process is unknown, certain environmental and genetic factors are known to be triggers. Disease management depends on disease severity, psychosocial effects and the patient\\'s lifestyle. To effectively treat this disease the nurse must be skilled in psoriasis management, and in patient education and motivation. This article reviews the characteristics, aetiology, psychosocial effects and treatment strategies of psoriasis.

    age was 25% (3-43%). In Salvador, where vaccine effectiveness was 34% (8-53%), vaccination of 381 children would prevent one case of tuberculosis and was cheaper than treatment. The frequency of adverse events was very low with only one axillary lymphadenitis and one ulcer greater than 1 cm in 11,980 BCG vaccinations. Vaccination of school-age children without previous tuberculin testing can reduce the incidence of tuberculosis and could reduce the costs of tuberculosis control. Restriction of BCG vaccination to the first year of life is not in the best interests of the public nor of programmes for tuberculosis control.

    The aim of this study was to assess the cost-effectiveness of pembrolizumab in treating patients with ipilimumab-naïve advanced melanoma in Portugal. A cost-effectiveness model was developed to analyze the costs and consequences of treatment with pembrolizumab compared to treatment with ipilimumab in patients with advanced melanoma not previously treated with ipilimumab. The model was parameterized by using data from a head-to-head phase III randomized clinical trial, KEYNOTE-006. Extrapolation of long-term outcomes was based on approaches previously applied, combining ipilimumab data and melanoma patients' registry data. The analysis was conducted from the perspective of the Portuguese National Health Service, and a lifetime horizon (40 years) was used. Portugal-specific disease management costs were estimated by convening a panel of six clinical experts to derive health state resource use and multiplying the results by national unit costs. To test for the robustness of the conclusions, we conducted deterministic and probabilistic sensitivity analyses. Pembrolizumab increases life expectancy in 1.57 undiscounted life-years (LYs) and is associated with an increase in costs versus that of ipilimumab. The estimated incremental cost-effectiveness ratio is €47,221 per quality-adjusted life-year (QALY) and €42,956 per LY. Deterministic sensitivity analysis showed that the results were robust to the change of most input values or assumptions and were sensitive to time on treatment scenarios. According to the probabilistic sensitivity analysis performed, pembrolizumab is associated with a cost per QALY gained inferior to €50,000 in 75% of the cases. Considering the usually accepted thresholds in oncology, pembrolizumab is a cost-effective alternative for treating patients with advanced melanoma in Portugal.

Since body weight balance is associated with changes in blood pressure (BP and fasting lipids, we have assessed these parameters following vildagliptin treatment. Methods: Data were pooled from all double-blind, randomized, controlled, vildagliptin monotherapy trials on previously drug-naïve patients with type 2 diabetes mellitus who received vildagliptin 50 mg once daily (qd or twice daily (bid; n=2,108 and wherein BP and fasting lipid data were obtained. Results: Data from patients receiving vildagliptin 50 mg qd or bid showed reductions from baseline to week 24 in systolic BP (from 132.5±0.32 to 129.8±0.34 mmHg; P<0.0001, diastolic BP (from 81.2±0.18 to 79.6±0.19 mmHg; P<0.0001, fasting triglycerides (from 2.00±0.02 to 1.80±0.02 mmol/L; P<0.0001, very low density lipoprotein cholesterol (from 0.90±0.01 to 0.83±0.01 mmol/L; P<0.0001, and low density lipoprotein cholesterol (from 3.17±0.02 to 3.04±0.02 mmol/L; P<0.0001, whereas high density lipoprotein cholesterol increased (from 1.19±0.01 to 1.22±0.01 mmol/L; P<0.001. Weight decreased by 0.48±0.08 kg (P<0.001. Conclusion: This large pooled analysis demonstrated that vildagliptin shows a significant reduction in BP and a favorable fasting lipid profile that are associated with modest weight loss.

    There is evidence from case studies suggesting that adapted dialectical behavior therapy (DBT) for borderline personality disorder (BPD) and eating disorders (ED) might improve disorder related complaints. Twenty-four women with BPD (9 with comorbid anorexia nervosa [AN] and 15 with bulimia nervosa [BN]), who already had failed to respond to previous eating-disorder related inpatient treatments were consecutively admitted to an adapted inpatient DBT program. Assessment points were at pre-treatment, post-treatment, and 15-month follow-up. At follow-up, the remission rate was 54% for BN, and 33% for AN. Yet 44% of women with AN crossed over to BN and one woman additionally met the criteria of AN. For women with AN, the mean weight was not significantly increased at post-treatment, but had improved at follow-up. For women with BN, the frequency of binge-eating episodes was reduced at post-treatment as well as at follow-up. Self-rated eating-related complaints and general psychopathology, as well as ratings on global psychosocial functioning, were significantly improved at post-treatment and at follow-up. Although these findings support the assumption that the adapted DBT inpatient program is a potentially efficacious treatment for those who failed to respond to previous eating-disorder related inpatient treatments, remission rates and maintained eating-related psychopathology also suggest that this treatment needs further improvement. 2010 Elsevier Ltd.

    Tremor is a common symptom of Parkinson's disease (PD). The underlying pathophysiology of parkinsonian rest tremor is not well understood. Rest tremor is less responsive to dopaminergic therapy than are symptoms of bradykinesia and rigidity. This paper reviews the effects of 1 mg daily oral rasagiline, as monotherapy and as adjunct therapy, on parkinsonian tremor. A literature search of the EMBASE database was conducted to identify relevant articles in English published between 2000 and October, 2012 using the search terms "rasagiline," or "Azilect®," or "Agilect®," and refined using the terms "Parkinson's disease" and "clinical trial." Of 22 identified publications, two large placebo-controlled trials of rasagiline monotherapy (TEMPO and ADAGIO) and two large placebo-controlled trials of rasagiline as adjunctive therapy with levodopa (PRESTO and LARGO) specifically evaluated the effect of rasagiline on tremor using the Unified Parkinson's Disease Rating Scale (UPDRS) motor examination. Prospective and post-hoc analyses from these phase III studies show rasagiline monotherapy significantly improved tremor symptoms in early PD, independent of disease duration, compared with placebo. In levodopa-treated patients with motor fluctuations who were already receiving optimized dopaminergic treatment, the addition of rasagiline adjunct therapy significantly improved tremor symptoms. Significant improvement was evident as early as 10 weeks from treatment initiation. Tremor symptoms also improved in a subset of patients with severe tremor when rasagiline was added to their existing PD treatment regimen. These data suggest that rasagiline used as monotherapy and as adjunctive therapy is effective for reducing tremor severity in patients with PD.

    The daily application of drugs, often in high doses, is a factor of stress for the infertile couple. During the last decade corifollitropin alpha has allowed a friendlier scheme comparable to traditional protocols (rFSH-HMG) results. To compare the results of corifollitropin alpha in patients with a previous cycle of IVF-ICSI with traditional scheme ovarian stimulation. Observational, retrospective cohort study type that infertile couples were included. No significant differences in the dose used HFRS (2023U/ total ± 712 vs 636 U/total ± 307) and serum estradiol day shooting HGCr (1972 pg/dL vs 1107 ± 1152 pg/dL ± 775). A higher pregnancy rate was found corifollitropin alpha perhaps because it was a second attempt at in vitro fertilization. Reproductive outcomes in a cycle of ovarian stimulation with corifollitropin are comparable with the results of a traditional ovarian stimulation cycle. It is important to broaden the experience of the drug indication in Mexican patients.

    Our primary objective was to prospectively evaluate anorectal symptoms, anal manometry and endoanal ultrasound (EAUS) in women who followed the recommended mode of subsequent delivery following index obstetric anal sphincter injuries (OASIs) using our unit's standardised protocol. Our secondary objectives were to evaluate the role of internal anal sphincter defects and also to compare outcomes in a subgroup of symptomatic women with normal anorectal physiology. This is a prospective follow-up study of pregnant women with previous OASIs who were counselled regarding subsequent mode of delivery between January 2003 and December 2014. Assessment involved the St Mark's Incontinence Score (SMIS), anal manometry and EAUS at both antepartum and 3-month postpartum visits. Data were analysed using Wilcoxon and Mann-Whitney U tests. Three hundred and fifty women attended the perineal clinic over the study period, of whom 122 met the inclusion criteria (99 vaginal delivery [VD], 23 caesarean section). No significant worsening of anorectal symptoms was observed following subsequent delivery in the VD group (p = 0.896), although a reduced squeeze pressure was observed at 3 months postpartum (p delivery. In the absence of a randomised study, use of this protocol can aid clinicians in their decision-making.

    One of the side effects of peritoneal photodynamic treatment (PDT) of mice is a systemic suppression of contact hypersensitivity (CH) responses. Treatment with either laser alone or the photosensitizer, Photofrin II (PFII), alone does not cause suppression of CH responses. Immunosuppression of CH responses is an active process that is adoptively transferable using viable cells, but not serum, from PDT-treated mice. The induction of adoptively transferable suppressor cells in PDT-treated mice requires exposure to an antigenic stimulus, yet the suppressor cells are antigen non-specific in their function. T cell function in PDT-treated mice, as measured by the ability of splenic lymphoid cells to generate allogeneic cytotoxic T lymphocyte responses, is comparable to that detected in normal mice. However, the ability of spleen cells from PDT-treated mice to act as stimulators in a mixed lymhocyte reaction is dramatically impaired, suggesting that the major cell type affected by peritoneal PDT is of the macrophage lineage. Support for this concept is provided by experiments in which spleen cells from PDT-treated mice were chromatographically separated into populations of T cells, B cells and macrophages prior to adoptive transfer into naive recipients. The results indicate that the cell type mediating adoptively transferable suppression of CH responsiveness is of the macrophage lineage. Analysis of hematologic parameters revealed that induction of suppression by PDT-treatment was associated with a marked neutrophilia and lymphocytosis, and was also accompanied by a 5-fold increase in concentration of the acute phase protein, Serum Amyloid P. Finally, attempts to ameliorate PDT-induced immunosuppression by pharmacologic intervention have proved successful using implants of pellets that release indomethacin at a rate of 1.25µg/day. Thus, the data suggest that PDT-treatment induces macrophages to produce factors (e.g., prostaglandins) that are known to be potently

    Soft tissue augmentation is one of the most frequent techniques in cosmetic dermatology. Nowadays, there are a high number of available materials. Nonanimal hyaluronic acid (HA) is one of most useful fillers for lip augmentation and for treating nasolabial folds, marionette lines, and the dynamic wrinkles of the upper face. To evaluate the type and management of undesirable effects of nonanimal reticulated or stabilized HA observed in our cosmetic unit in the past 3 years. The consecutive patients using HA attending to our clinic in the past 3 years were divided into 3 categories, according to the time of presentation of the adverse reactions: immediate, early, and late-onset complications. All patients were treated. Twenty-three patients presented to our clinic complaining of complications after soft tissue augmentation with HA. Ten patients presented immediate-onset complications, 8 showed early-onset complications, and 5 cases complaint of late-onset complications. Treatment of the first group consisted of hyaluronidase injection, massage, and topical antibiotics. Early- and late-onset complications were treated with intralesional triamcinolone acetonide. All patients improved, with the exception of a woman with recurrent granulomas. Generally, undesirable effects of HA (immediate, early, or late onset) are not frequent, and when present, they improve if treated properly. Physicians need to be aware of these possible adverse events in order to establish proper treatment and prevent scarring or other sequelae.

    The aims of this study were to investigate the safety of combined intravenous, oral and topical tranexamic acid (TXA) in primary total knee replacement. We assessed dose-related efficacy on hemoglobin level, transfusion, length of stay and thromboembolic complications. In addition, TXA safety in patients with previous history of thromboembolism >12months ago was monitored specifically. From January 2013 until January 2016, 922 patients were included who received TXA after primary total knee replacement. Patients without TXA administration or with thromboembolic events dosage groups were divided into ≤10mg/kg, >10-25mg/kg and >25-50mg/kg. Between the three TXA groups no significant difference was found in thromboembolic complications (deep venous thrombosis (DVT) and pulmonary embolism (PE)), wound leakage and transfusion rate. For patients with DVT or PE in their history >12months ago specifically, no more complications were noted in higher-TXA-dosage groups compared to the low-dosage group. Length of stay was shorter in the highest-TXA-dosage group compared with lower-dosage groups (median two vs three days). With high TXA dose a smaller difference between pre- and postoperative Hb was found: the >25-50mg/kg TXA group had a 0.419mmol/l smaller decrease in postoperative hemoglobin compared to the lowest-dosage group (P12months ago. High dosage (>25-50mg/kg) TXA resulted in the smallest decrease in postoperative hemoglobin. Copyright © 2017 Elsevier B.V. All rights reserved.

    High plasma total homocysteine (tHcy) has been associated with cognitive impairment but lowering tHcy with B-vitamins has produced equivocal results. We aimed to determine whether B-vitamin supplementation would reduce tHcy and the incidence of new cognitive impairment among individuals with stroke or transient ischemic attack≥6 months previously. A total of 8164 patients with stroke or transient ischemic attack were randomly allocated to double-blind treatment with one tablet daily of B-vitamins (folic acid, 2 mg; vitamin B6, 25 mg; vitamin B12, 500 μg) or placebo and followed up for 3.4 years (median) in the VITAmins TO Prevent Stroke (VITATOPS) trial. For this prespecified secondary analysis of VITATOPS, the primary outcome was a new diagnosis of cognitive impairment, defined as a Mini-Mental State Examination (MMSE) score6 months after the qualifying stroke; 2608 participants were cognitively unimpaired (MMSE≥24), of whom 2214 participants (1110 B-vitamins versus 1104 placebo) had follow-up MMSEs during 2.8 years (median). At final follow-up, allocation to B-vitamins, compared with placebo, was associated with a reduction in mean tHcy (10.2 μmol/L versus 14.2 μmol/L; Pvitamin B6, and vitamin B12 to a self-selected clinical trial cohort of cognitively unimpaired patients with previous stroke or transient ischemic attack lowered mean tHcy but had no effect on the incidence of cognitive impairment or cognitive decline, as measured by the MMSE, during a median of 2.8 years.

    2014-08-01

    Dysphagia remains a common problem in Parkinson's disease (PD). Previous systematic reviews on therapy effects for oropharyngeal dysphagia in PD have shown a lack of evidence. In the past 5 years several placebo or sham-controlled trials with varying results have been published. The aim of this systematic literature review is to summarize and qualitatively analyze the published studies on this matter. Studies published up to December 2013 were found via a systematic comprehensive electronic database search using PubMed, Embase, and The Cochrane Library. Two reviewers independently assessed the studies using strict inclusion criteria. Twelve studies were included and qualitatively analyzed using critical appraisal items. The review includes rehabilitative (exercises, electrical stimulation, bolus modification etc.) and pharmacologic treatment. Some well-designed controlled trials were included. However, none of the included studies fulfilled all criteria for external and internal validity. A meta-analysis was not carried out as most of the studies were not of sufficient quality to warrant doing so. Expiratory Muscle Strength Training (EMST) and Video-Assisted Swallowing Therapy (VAST) may be effective dysphagia treatments solely or in addition to dopaminergic therapy for PD. However, these preliminary results warrant further investigation concerning their clinical applicability, and further research should be based on randomized sham-controlled trials to determine the effectiveness and long-term effects of different therapies for dysphagia in PD.

    It has been suggested that sunlight through production of vitamin D might have a protective effect on a number of internal cancers. Consequently, in spite of the well known skin cancer risks, some researchers advocate more exposure to ultraviolet radiation, supported by the solarium industry. We estimated the risk of internal cancer before the patient contracted a basal cell carcinoma (BCC) of the skin, the most common cancer in white populations and strongly associated with extensive sun exposure. A nested case control study was undertaken in the whole Swedish population. 115,016 patients with BCC and 987,893 controls were linked to population based registers. The cases had an increased risk of getting another form of cancer before the BCC diagnosis: odds ratio (OR)=1.84; 95% confidence interval (CI) 1.81-1.86. This risk was mainly due to skin cancer: OR=4.95; 95% CI 4.81-5.09 but also non-skin cancer risk was elevated: OR=1.37; 95% CI 1.35-1.39. We adjusted the estimates for age, level of income, occupational status in national censuses, place of living and sex, where appropriate. Of the cancers specifically suggested to be related to vitamin D status: colon, prostate, breast, and ovary cancer, all had slightly increased ORs whilst for pancreatic and gastric cancer no increased OR was found. Patients with BCC, a proxy for extensive sun exposure, run an increased risk of other forms of cancer prior to the diagnosis of BCC. The findings in this study contradict that vitamin D production through extensive sun exposure has any protective effect on internal cancer but emphasise the increased risk for skin cancer.

    In the analytical treatment of the runaway-effect there appear the integrals Isub(m)(α). For m = 1, 2 and 3, series expansions for these integrals can be found in the literature. Furthermore, asymptotic solutions for Isub(m)(α) are known. It is shown here that the solutions for Isub(m)(α) can be approximated by the modified Bessel Function Ksub(n)(αsup(ν)) in such a way that for α → 0 the exact limiting value for Isub(m)(α) follows and that for α → infinite essentially the known asymptotic solutions for Isub(m)(α) follow. The maximum error for this approximation in the order of percent is considered justifiable for the application considered. (orig.)

  14. The effects of periodontal treatment on diabetes.

    Science.gov (United States)

    Taylor, George W

    2003-10-01

    Diabetes mellitus and periodontal diseases are common chronic diseases in the United States. Periodontal infection may adversely affect glycemic control in people with diabetes. This article reviews the evidence regarding how treatment of periodontal diseases affects glycemic control. The review consisted of a MEDLINE literature search to identify primary research reports on the relationship between periodontal therapy and changes in glycemic control. The review identified three randomized clinical trials and nine nonrandomized clinical follow-up studies. The strength, quantity and breadth of evidence are varied, precluding clear-cut guidance for determining whether treating periodontal infection has a beneficial effect on glycemic control. Despite the variation and limitations in the literature, evidence supports the concept that periodontal diseases can contribute to poorer glycemic control in people with diabetes. Although the evidence is not unequivocal, it provides sufficient support for additional investigations of the effect of preventing and treating periodontal infections on managing glycemic control. Sufficient evidence exists to incorporate oral examinations and periodontal care in management regimens for people with diabetes. It is prudent to assess patients' glycemic control status and communicate the importance of referring patients with diabetes for thorough oral health evaluations and necessary care.

    According to current medical opinion chronic mental diseases such as schizophrenia require life-long treatment. The choice of antipsychotics is an important treatment factor, since their side-effects often influence patients' compliance with treatment. Severe side-effects may cause the patients to reject such treatment, the latter being their right. In case a psychiatrist does not agree with the patient's decision to interrupt his antipsychotic treatment regardless its serious side-e...

    1982-01-01

    Archival data from the Sex Therapy Center at Stony Brook were analyzed to determine the prevalence of desire phase sexual dysfunctions and the effectiveness of treating them with behavioral sex therapy. When cases were rediagnosed with a multi-axial problem-oriented system, increases from 1974-1981 in both the prevalence of desire phase problems and of male low sexual desire were observed. Data suggested that wives display more extreme patterns of sexual avoidance than do husbands in couples seeking sex therapy. Outcome statistics on marital adjustment, overall sexual satisfaction, the frequency of intercourse and masturbation, and patterns of initiation of sexual activity reveal significant positive changes after treatment. These changes are not due to nonspecific factors and are maintained at follow-up. Sex therapy was equally successful for male-centered vs. female-centered problems, for low sexual desire vs. aversion to sex, and for global or lifelong dysfunctions vs. the more recent or situational ones. Posttreatment gains reflect a minimally adequate sexual relationship, however, rather than an optimal degree of intimacy and pleasure.

  19. Psychological mechanisms of effective cognitive-behavioral treatments for PTSD.

    Science.gov (United States)

    Zalta, Alyson K

    2015-04-01

    Several psychotherapies have been established as effective treatments for posttraumatic stress disorder (PTSD) including prolonged exposure, cognitive processing therapy, and cognitive therapy for PTSD. Understanding the key mechanisms of these treatments, i.e., how these treatments lead to therapeutic benefits, will enable us to maximize the efficacy, effectiveness, and efficiency of these therapies. This article provides an overview of the theorized mechanisms for each of these treatments, reviews the recent empirical evidence on psychological mechanisms of these treatments, discusses the ongoing debates in the field, and provides recommendations for future research. Few studies to date have examined whether changes in purported treatment mechanisms predict subsequent changes in treatment outcomes. Future clinical trials examining treatments for PTSD should use study designs that enable researchers to establish the temporal precedence of change in treatment mechanisms prior to symptom reduction. Moreover, further research is needed that explores the links between specific treatment components, underlying change mechanisms, and treatment outcomes.

    The authors hypothesized that patients with metastatic colorectal cancer (mCRC) who had tumors with low thymidylate synthase (TS-L) expression would have a higher response rate to combined 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) plus bevacizumab (FOLFOX/Bev) than those with high TS (TS-H) expression and that combined irinotecan and oxaliplatin (IROX) plus bevacizumab (IROX/Bev) would be more effective than FOLFOX/Bev in those with TS-H tumors. TS protein expression was determined in mCRC tissue. Patients who had TS-L tumors received FOLFOX/Bev, and those who had TS-H tumors were randomly assigned to receive either FOLFOX/Bev or IROX/Bev. The primary endpoint was the response rate (complete plus partial responses). In total, 211 of 247 patients (70% TS-H) were registered to the treatment phase. Efficacy analyses included eligible patients who had started treatment (N = 186). The response rates for patients who received IROX/Bev (TS-H), FOLFOX/Bev (TS-H), and FOLFOX/Bev (TS-L) were 33%, 38%, and 49%, respectively (P = nonsignificant). The median progression-free survival (PFS) was 10 months (95% confidence interval [CI], 9-12 months; 10 months in the IROX/Bev TS-H group, 9 months in the FOLFOX/Bev TS-H group, and 13 months in the FOLFOX/Bev TS-L group). The TS-L group had improved PFS compared with the TS-H group that received FOLFOX/Bev (hazard ratio, 1.6; 95% CI, 1.0%-2.4%; P = .04; Cox regression). The median overall survival (OS) was 22 months (95% CI, 20 29 months; 18 months in the IROX/Bev TS-H group, 21 months in the FOLFOX/Bev TS-H group, and 32 months in the TS-L group). OS comparisons for the 2 TS-H arms and for the FOLFOX/Bev TS-H versus TS-L arms were not significantly different. TS expression was prognostic: Patients with TS-L tumors who received FOLFOX/Bev had a longer PFS than those with TS-H tumors, along with a trend toward longer OS. Patients with TS-H tumors did not benefit more from IROX/Bev than from FOLFOX/Bev. Cancer 2018

    Previous studies have suggested that any benefits of folic acid-based therapy to lower serum homocysteine in prevention of cardiovascular events might be offset by concomitant use of antiplatelet therapy. We aimed to establish whether there is an interaction between antiplatelet therapy and the effects of folic acid-based homocysteine-lowering therapy on major vascular events in patients with stroke or transient ischaemic attack enrolled in the vitamins to prevent stroke (VITATOPS) trial. In the VITATOPS trial, 8164 patients with recent stroke or transient ischaemic attack were randomly allocated to double-blind treatment with one tablet daily of placebo or B vitamins (2 mg folic acid, 25 mg vitamin B(6), and 500 μg vitamin B(12)) and followed up for a median 3·4 years (IQR 2·0-5·5) for the primary composite outcome of stroke, myocardial infarction, or death from vascular causes. In our post-hoc analysis of the interaction between antiplatelet therapy and the effects of treatment with B vitamins on the primary outcome, we used Cox proportional hazards regression before and after adjusting for imbalances in baseline prognostic factors in participants who were and were not taking antiplatelet drugs at baseline and in participants assigned to receive B vitamins or placebo. We also assessed the interaction in different subgroups of patients and different secondary outcomes. The VITATOPS trial is registered with ClinicalTrials.gov, number NCT00097669, and Current Controlled Trials, number ISRCTN74743444. At baseline, 6609 patients were taking antiplatelet therapy and 1463 were not. Patients not receiving antiplatelet therapy were more likely to be younger, east Asian, and disabled, to have a haemorrhagic stroke or cardioembolic ischaemic stroke, and to have a history of hypertension or atrial fibrillation. They were less likely to be smokers and to have a history of peripheral artery disease, hypercholesterolaemia, diabetes, ischaemic heart disease, and a

    Background and purpose - Patients with osteoporosis who present with an acute onset of back pain often have multiple fractures on plain radiographs. Differentiation of an acute osteoporotic vertebral fracture (AOVF) from previous fractures is difficult. The aim of this study was to investigate the incidence of concomitant AOVFs and previous OVFs in patients with symptomatic AOVFs, and to identify risk factors for concomitant AOVFs. Patients and methods - This was a prospective epidemiological study based on the Registry of Pathological Osteoporotic Vertebral Fractures (REPAPORA) with 1,005 patients and 2,874 osteoporotic vertebral fractures, which has been running since February 1, 2006. Concomitant fractures are defined as at least 2 acute short-tau inversion recovery (STIR-) positive vertebral fractures that happen concomitantly. A previous fracture is a STIR-negative fracture at the time of initial diagnostics. Logistic regression was used to examine the influence of various variables on the incidence of concomitant fractures. Results - More than 99% of osteoporotic vertebral fractures occurred in the thoracic and lumbar spine. The incidence of concomitant fractures at the time of first patient contact was 26% and that of previous fractures was 60%. The odds ratio (OR) for concomitant fractures decreased with a higher number of previous fractures (OR =0.86; p = 0.03) and higher dual-energy X-ray absorptiometry T-score (OR =0.72; p = 0.003). Interpretation - Concomitant and previous osteoporotic vertebral fractures are common. Risk factors for concomitant fractures are a low T-score and a low number of previous vertebral fractures in cases of osteoporotic vertebral fracture. An MRI scan of the the complete thoracic and lumbar spine with STIR sequence reduces the risk of under-diagnosis and under-treatment.

    Several factors can affect oocyte quality and therefore pregnancy outcome in assisted reproductive technology (ART) cycles. Recently, a number of studies have shown that the presence of several compounds in the follicular fluid positively correlates with oocyte quality and maturation (i.e., myo-inositol and melatonin). In the present study, we aim to evaluate the pregnancy outcomes after the administration of myo-inositol combined with melatonin in women who failed to conceive in previous in vitro fertilization (IVF) cycles due to poor oocyte quality. Forty-six women were treated with 4 g/day myo-inositol and 3 mg/day melatonin (inofolic® and inofolic® Plus, Lo.Lipharma, Rome) for 3 months and then underwent a new IVF cycle. After treatment, the number of mature oocytes, the fertilization rate, the number of both, total and top-quality embryos transferred were statistically higher compared to the previous IVF cycle, while there was no difference in the number of retrieved oocyte. After treatment, a total of 13 pregnancies occurred, 9 of them were confirmed echographically; four evolved in spontaneous abortion. The treatment with myo-inositol and melatonin improves ovarian stimulation protocols and pregnancy outcomes in infertile women with poor oocyte quality.

    Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous entity, showing a highly variable outcome. In patients with DLBCL relapsed/refractory to first-line treatment with rituximab the usefulness of the revised International Prognostic Index (R-IPI) as a prognostic tool remains unexplored. Some biological parameters (B-cell lymphoma 6 [Bcl-6], Bcl-2, p53, and multiple myeloma 1 [MUM1]) and blood populations (lymphocyte and monocyte counts) have been described as International Prognostic Index-independent prognostic factors. The objective was to evaluate the R-IPI to predict the outcome of DLBCL patients at the time of relapse after a front-line treatment with chemotherapy and rituximab and to establish in this population the relationship between biological parameters and outcome. We included patients with refractory/relapsed DLBCL after first-line treatment with rituximab-containing regimens; patients must have already finished a rescue treatment also including rituximab. Immunohistochemical assessment of Bcl-2, Bcl-6, p53, and MUM1 expression were undertaken in available biopsies. R-IPI factors were identified from the clinical data at diagnosis and at relapse. Response was assessed using National Cancer Institute-sponsored Working Group guidelines. R-IPI prognosis at relapse was not significantly associated with overall response rate (ORR) after Rituximab-chemotherapy rescue therapy. None of the immunohistochemical parameters analyzed correlated with rescue therapy results. In contrast, patients with absolute lymphocyte count (ALC) ≥ 1 × 10(9)/L at relapse were more likely to respond than patients with ALC IPI score calculated at relapse could not predict the ORR to second-line treatment. Lymphopenia is a simple and useful predictor for outcome in relapsed/refractory DLBCL and the only prognostic factor that in our hands could predict the overall response to a second-line treatment with rituximab and chemotherapy.

    The study was designed to investigate how the periodontal disease treatment with Emdogain may influence the parameters of serum acute phase response and the total antioxidant status (TAS) of nonstimulated saliva. The wound healing process after periodontal treatment provided with EMD and regular open flap procedure was observed in 28 patients. TAS in saliva and acute phase proteins in blood was measured before and after treatment. The PD varied from 3,91 mm before treatment to 1,27 after it in EMD group and from 3,83 mm and 1,33 in the control group. CAL varied from 3,2 - 2,4 mm in EMD group and from 2,70 - 2,2 in the control group (p<0,01 and p<0,001). On the basis and after treatment of acute phase proteins analysis existence of chronic inflammatory state with slight decreased total concentration of AGP, ACP. Low TAS level found in the saliva of the subjects in our study may suggest that the antioxidant defence of saliva in patients with chronic periodontitis is poor.

  12. Psychiatric side effects of interferon treatment.

    Science.gov (United States)

    Patten, Scott B

    2006-05-01

    Interferons are employed in the management of multiple sclerosis, hepatitis C and certain malignancies. Neuropsychiatric toxicity can interfere with the successful use of these drugs. This review was based on Medline literature searches, supplemented by bibliographical citations in identified papers. Information uncovered in the literature review was interpreted in light of related pharmacoepidemiological and psychiatric literature. Interferon-associated neurotoxicity does not adhere closely to standard psychiatric syndromal and diagnostic definitions. Delirium, depression, non-specific symptoms related to sickness behavior and, rarely, manic and psychotic syndromes are all potential adverse events during interferon treatment. For depression, the evidence of increased risk is stronger for interferon alpha than for interferon beta. The availability of preventive and treatment interventions suggest that neuropsychiatric toxicity can often be managed without needing to discontinue the treatment. Safety can be maximized by organization of health services in ways that enhance detection and management of neuropsychiatric problems, and which support access to basic and specialized mental health services.

    In Gujarat, India, a state led public private partnership scheme to promote facility birth named Chiranjeevi Yojana (CY) was implemented in 2005. Institutional birth is provided free of cost at accredited private health facilities to women from socially disadvantaged groups (eligible women). CY has contributed in increasing facility birth and providing substantially subsidized (but not totally free) birth care; however, the retention of mothers in this scheme in subsequent child birth is unknown. Therefore, we conducted a study aimed to determine the effect of previous utilization of the scheme and previous out of pocket expenditure on subsequent child birth among multiparous eligible women in Gujarat. This was a retrospective cohort study of multiparous eligible women (after excluding abortions and births at public facility). A structured questionnaire was administered by trained research assistant to those with recent delivery between Jan and Jul 2013. Outcome of interest was CY utilization in subsequent child birth (Jan-Jul 2013). Explanatory variables included socio-demographic characteristics (including category of eligibility), pregnancy related characteristics in previous child birth, before Jan 2013, (including CY utilization, out of pocket expenditure) and type of child birth in subsequent birth. A poisson regression model was used to assess the association of factors with CY utilization in subsequent child birth. Of 997 multiparous eligible women, 289 (29%) utilized and 708 (71%) did not utilize CY in their previous child birth. Of those who utilized CY (n = 289), 182 (63%) subsequently utilized CY and 33 (11%) gave birth at home; whereas those who did not utilize CY (n = 708) had four times higher risk (40% vs. 11%) of subsequent child birth at home. In multivariable models, previous utilization of the scheme was significantly associated with subsequent utilization (adjusted Relative Risk (aRR): 2.7; 95% CI: 2.2-3.3), however previous out of pocket

    2015-01-01

    This paper considers conducting inference about the effect of a treatment (or exposure) on an outcome of interest. In the ideal setting where treatment is assigned randomly, under certain assumptions the treatment effect is identifiable from the observable data and inference is straightforward. However, in other settings such as observational studies or randomized trials with noncompliance, the treatment effect is no longer identifiable without relying on untestable assumptions. Nonetheless, the observable data often do provide some information about the effect of treatment, that is, the parameter of interest is partially identifiable. Two approaches are often employed in this setting: (i) bounds are derived for the treatment effect under minimal assumptions, or (ii) additional untestable assumptions are invoked that render the treatment effect identifiable and then sensitivity analysis is conducted to assess how inference about the treatment effect changes as the untestable assumptions are varied. Approaches (i) and (ii) are considered in various settings, including assessing principal strata effects, direct and indirect effects and effects of time-varying exposures. Methods for drawing formal inference about partially identified parameters are also discussed. PMID:25663743

    Full Text Available Background Epilepsy remains one of the most frequently occurring pediatric problems. Approximately 10-15% patients do not respond to conventional therapy. Topiramate as a novel antiepileptic drug has a broad spectrum activity, presumably indicative of multiple anti-seizure mechanisms. Previous studies of topiramate as adjunctive and monotherapy in adults have shown beneficial effects. The objective of this research was to evaluate the efficacy and tolerability of topiramate sprinkle monotherapy in pediatric epilepsy. Methods This experimental research was conducted in the Pediatric Neurology outpatient clinic department, Soetomo hospital, Surabaya, involving 18 consecutive subjects. Subjects meeting the inclusion criteria were treated with topiramate sprinkle adjusted dose. Seizure frequency and side effects were observed in weeks 1, 4, 8, 12, 16, 20 and 24, respectively. Electro encephalogram (EEG and laboratory examinations were performed prior to and after 6 months of treatment. The t-test for related samples and McNemar test were utilized for statistical analysis. Results A total of 15 subjects completed the study. Topiramate-treated patients showed a statistically significant difference of seizure frequency reduction from 2.7 ± 1.16 to 0.13 ± 0.51 (p=0.000 with 93.7% patients being seizure free in 20 weeks. EEG recordings did not differ statistically in decrement of epileptiform activity in 20% subjects. About 7% subjects developed drowsiness and 33.3% subjects suffered from appetite suppression in the initial treatment. Laboratory results showed no abnormalities. Conclusions There was reduction of seizure frequency and no EEG recording alterations after topiramate sprinkle monotherapy. Topiramate as a monotherapy is highly effcicacious in childhood epilepsy.

    Treatment options for prostate cancer consist of radical prostatectomy, hormonal therapy and radiation therapy. Hormonal and radiation therapy have well-known, often profound, effects on the histological appearance of benign and malignant prostate tissue. Novel therapies including focal ablative treatments, chemotherapies and targeted molecular therapies are beginning to emerge and pathologists will play a central role in documenting the effects of these treatments at the tissue level. As such, knowledge of treatment-related changes and access to clinical information are essential to ensure accurate interpretation and reporting of post-treatment prostate specimens by pathologists.

    Research relative to the efficacy of a therapeutic agent commands a clinician's greatest interest, but treatment decisions are made based on optimizing efficacy and tolerability/safety considerations. Second-generation atypical antipsychotic drugs are a study in the importance of taking a careful look at the full benefit-risk profile of each drug. The disorders that atypical antipsychotics are approved to treat--schizophrenia, schizoaffective disorder, and bipolar disorder--are associated with an increased rate of certain medical comorbidities compared to the general population. Between-drug differences in efficacy are relatively modest for the atypicals, or between atypicals and conventionals, while differences in safety and tolerability are larger and more clinically relevant. The current article will provide a brief summary of safety-related issues that influence treatment outcome and choice of drug.

    Background Recent studies suggest that the protective effect of the current influenza vaccine could be influenced by vaccination in previous seasons. We estimated the combined effect of the previous and current influenza vaccines from the 2010–2011 season to the 2015–2016 season in Spain. Methods We performed a test-negative case-control study in patients ≥9 years old. We estimated the influenza vaccine effectiveness (IVE) against influenza A(H1N1)pdm09, A(H3N2), and B virus. Results We included 1206 influenza A(H1N1)pdm09 cases, 1358 A(H3N2) cases and 1079 B cases. IVE against A(H1N1)pdm09 virus in the pooled-season analysis was 53% (95% Confidence Interval (CI): 21% to 72%) for those vaccinated only in the current season and 50% (95%CI: 23% to 68%) for those vaccinated in the both current and previous seasons. Against the influenza A(H3N2) virus, IVE was 17% (95%CI: -43% to 52%) for those vaccinated only in the current season and 3% (95%CI: -33% to 28%) for those vaccinated in both seasons. Regarding influenza B, we obtained similar IVEs for those vaccinated only in the current and those vaccinated in both seasons: 57% (95%CI: 12% to 79%) and 56% (95%CI: 36% to 70%), respectively. Conclusion Our results suggested no interference between the previous and current influenza vaccines against A(H1N1)pdm09 and B viruses, but a possible negative interference against A(H3N2) virus.

    Derman, Rifka C; Ferrario, Carrie R

    2018-03-16

    Efforts to stem the global rise in obesity have been minimally effective, perhaps in part because our understanding of the psychological and behavioral drivers of obesity is limited. It is well established that stimuli that are paired with palatable foods can powerfully influence food-seeking and feeding behaviors. However, how consumption of sugary, fatty "junk-foods" affects these motivational responses to food cues is poorly understood. Here, we determined the effects of short- and long-term "junk-food" consumption on the expression of cue potentiated feeding and conditioned food cup approach to Pavlovian conditioned stimuli (CS). Further, to determine the degree to which effects of "junk-food" were selective to Pavlovian motivational processes, we varied the predictive validity of the CS by including training groups conditioned with unique CS-US contingencies ranging from -1.0 to +1.0. "Junk-food" did not enhance cue potentiated feeding in any group, but expression of this potentiation effect varied with the CS-US contingency independent of diet. In contrast, "junk-food" consistently enhanced conditioned approach to the food cup; this effect was dependent on the previously established CS-US contingency. That is, consumption of "junk-food" following training enhanced approach to the food cup only in response to CSs with previously positive CS-US contingencies. This was accompanied by reduced motivation for the US itself. Together these data show that "junk-food" consumption selectively enhances incentive motivational responses to previously established food CSs, without altering cue potentiated feeding induced by these same CSs, and in the absence of enhanced motivation for food itself.

    To investigate the effect of sequential treatment escalation with empagliflozin and linagliptin on laboratory markers of α- and β-cell function in people with type 2 diabetes mellitus (T2DM) insufficiently controlled on metformin monotherapy. A total of 44 people with T2DM received 25 mg empagliflozin for a duration of 1 month in an open-label fashion (treatment period 1 [TP1]). Thereafter, they were randomized to a double-blind add-on therapy with linagliptin 5 mg or placebo (treatment period 2 [TP2]) for 1 additional month. α- and β-cell function was assessed using a standardized liquid meal test and an intravenous (i.v.) glucose challenge. Efficacy measures comprised the areas under the curve for glucose, insulin, proinsulin and glucagon after the liquid meal test and the assessment of fast and late-phase insulin release after an i.v. glucose load with a subsequent hyperglycaemic clamp. Empagliflozin reduced fasting and postprandial plasma glucose levels, associated with a significant reduction in postprandial insulin levels and an improvement in the conversion rate of proinsulin (TP1). The addition of linagliptin during TP2 further improved postprandial glucose levels, probably as a result of a marked reduction in postprandial glucagon concentrations (TP2). The insulin response to an i.v. glucose load increased during treatment with empagliflozin (TP1), and further improved after the addition of linagliptin (TP2). After metformin failure, sequential treatment escalation with empagliflozin and linagliptin is an attractive treatment option because of the additive effects on postprandial glucose control, probably mediated by complementary effects on α- and β-cell function. © 2016 John Wiley & Sons Ltd.

  12. Asymmetric inhibitory treatment effects in multilingual aphasia.

    Findings from recent psycholinguistic studies of bilingual processing support the hypothesis that both languages of a bilingual are always active and that bilinguals continually engage in processes of language selection. This view aligns with the convergence hypothesis of bilingual language representation. Furthermore, it is hypothesized that when bilinguals perform a task in one language they need to inhibit their other, nontarget language(s) and that stronger inhibition is required when the task is performed in the weaker language than in the stronger one. The study of multilingual individuals who acquire aphasia resulting from a focal brain lesion offers a unique opportunity to test the convergence hypothesis and the inhibition asymmetry. We report on a trilingual person with chronic nonfluent aphasia who at the time of testing demonstrated greater impairment in her first acquired language (Persian) than in her third, later learned language (English). She received treatment in English followed by treatment in Persian. An examination of her connected language production revealed improvement in her grammatical skills in each language following intervention in that language, but decreased grammatical accuracy in English following treatment in Persian. The increased error rate was evident in structures that are used differently in the two languages (e.g., auxiliary verbs). The results support the prediction that greater inhibition is applied to the stronger language than to the weaker language, regardless of their age of acquisition. We interpret the findings as consistent with convergence theories that posit overlapping neuronal representation and simultaneous activation of multiple languages and with proficiency-dependent asymmetric inhibition in multilinguals.

  14. Continuum treatment of electronic polarization effect.

    2007-03-07

    A continuum treatment of electronic polarization has been explored for in molecular mechanics simulations in implicit solvents. The dielectric constant for molecule interior is the only parameter in the continuum polarizable model. A value of 4 is found to yield optimal agreement with high-level ab initio quantum mechanical calculations for the tested molecular systems. Interestingly, its performance is not sensitive to the definition of molecular volume, in which the continuum electronic polarization is defined. In this model, quantum mechanical electrostatic field in different dielectric environments from vacuum, low-dielectric organic solvent, and water can be used simultaneously in atomic charge fitting to achieve consistent treatment of electrostatic interactions. The tests show that a single set of atomic charges can be used consistently in different dielectric environments and different molecular conformations, and the atomic charges transfer well from training monomers to tested dimers. The preliminary study gives us the hope of developing a continuum polarizable force field for more consistent simulations of proteins and nucleic acids in implicit solvents.

    We analyze the Lipkin model in the strong coupling limit using effective operator techniques. We present both analytical and numerical results for low energy effective Hamiltonians. We investigate the reliability of various approximations used to simplify the nuclear many body problem, such as the cluster approximation. We demonstrate, in explicit examples, certain limits to the validity of the cluster approximation but caution that these limits may be particular to this model where the interactions are of unlimited range

    Falk Schwendicke

    Full Text Available OBJECTIVES: Invasive therapy of proximal caries lesions initiates a cascade of re-treatment cycles with increasing loss of dental hard tissue. Non- and micro-invasive treatment aim at delaying this cascade and may thus reduce both the health and economic burden of such lesions. This study compared the costs and effectiveness of alternative treatments of proximal caries lesions. METHODS: A Markov-process model was used to simulate the events following the treatment of a proximal posterior lesion (E2/D1 in a 20-year-old patient in Germany. We compared three interventions (non-invasive; micro-invasive using resin infiltration; invasive using composite restoration. We calculated the risk of complications of initial and possible follow-up treatments and modelled time-dependent non-linear transition probabilities. Costs were calculated based on item-fee catalogues in Germany. Monte-Carlo-microsimulations were performed to compare cost-effectiveness of non- versus micro-invasive treatment and to analyse lifetime costs of all three treatments. RESULTS: Micro-invasive treatment was both more costly and more effective than non-invasive therapy, with ceiling-value-thresholds for willingness-to-pay between 16.73 € for E2 and 1.57 € for D1 lesions. Invasive treatment was the most costly strategy. Calculated costs and effectiveness were sensitive to lesion stage, patient's age, discounting rate and assumed initial treatment costs. CONCLUSIONS: Non- and micro-invasive treatments have lower long-term costs than invasive therapy of proximal lesions. Micro-invasive therapy had the highest cost-effectiveness for treating D1 lesions in young patients. Decision makers with a willingness-to-pay over 16.73 € and 1.57 € for E2 and D1 lesions, respectively, will find micro-invasive treatment more cost-effective than non-invasive therapy.

    Medical treatments take place in social contexts; however, little research has investigated how social modelling might influence treatment outcomes. This experimental pilot study investigated social modelling of treatment effectiveness and placebo treatment outcomes. Fifty-nine participants took part in the study, ostensibly examining the use of beta-blockers (actually placebos) for examination anxiety. Participants were randomly assigned to observe a female confederate report positive treatment effects (reduced heart rate, relaxed, calm) or feeling no different. Heart rate, anxiety and blood pressure were assessed, as were symptoms and attributed side effects. Heart rate decreased significantly more in the social modelling compared to control condition, p = .027 (d = .63), and there were trends towards effects in the same direction for both anxiety, p = .097 (d = .46), and systolic blood pressure, p = .077 (d = .51). Significant pre-post placebo differences in heart rate, anxiety and diastolic blood pressure were found in the social modelling group, ps  .28 (ds = .09-.59). Social observation of medication effectiveness enhanced placebo effectiveness in heart rate, and showed a trend towards enhancing treatment effectiveness in both anxiety and systolic blood pressure. Social modelling may have utility in enhancing the effectiveness of many active medical treatments.

    Metallic Zn nanodisks with hexagonal morphology were obtained onto glass substrate under vacuum thermal evaporation. A thermal characterization of Zn nanodiks showed a lower oxidation temperature than source powder Zn. Different thermal treatment on Zn nanodisks played an important role on the morphology, crystal size and surface vibrational modes of ZnO. The growth of ZnO nanoneedles started at the edge of metallic zinc hexagonal structures according with SEM images, the higher temperature the longer needles were grown. XRD diffractogram confirmed the wurtzite structure of ZnO with metallic nuclei. A wide band between 530 and 580 cm{sup −1} of Raman scattering corresponded at surface vibrational modes not observed at higher temperature.

    Fibromyalgia syndrome (FMS) is a chronic, idiopathic condition of widespread musculoskeletal pain, affecting primarily women. It is clinically characterized by chronic, nonarticular pain and a heightened response to pressure along with sleep disturbances, fatigue, bowel and bladder abnormalities, and cognitive dysfunction. The diagnostic criteria have changed repeatedly, and there is neither a definitive pathogenesis nor reliable diagnostic or prognostic biomarkers. Clinical and laboratory studies have provided evidence of altered central pain pathways. Recent evidence suggests the involvement of neuroinflammation with stress peptides triggering the release of neurosenzitizing mediators. The management of FMS requires a multidimensional approach including patient education, behavioral therapy, exercise, and pain management. Here we review recent data on the pathogenesis and propose new directions for research and treatment. PMID:26306765

    Despite widespread implementation of compulsory treatment modalities for drug dependence, there has been no systematic evaluation of the scientific evidence on the effectiveness of compulsory drug treatment. We conducted a systematic review of studies assessing the outcomes of compulsory treatment. We conducted a search in duplicate of all relevant peer-reviewed scientific literature evaluating compulsory treatment modalities. The following academic databases were searched: PubMed, PAIS International, Proquest, PsycINFO, Web of Science, Soc Abstracts, JSTOR, EBSCO/Academic Search Complete, REDALYC, SciELO Brazil. We also searched the Internet, and article reference lists, from database inception to July 15th, 2015. Eligibility criteria are as follows: peer-reviewed scientific studies presenting original data. Primary outcome of interest was post-treatment drug use. Secondary outcome of interest was post-treatment criminal recidivism. Of an initial 430 potential studies identified, nine quantitative studies met the inclusion criteria. Studies evaluated compulsory treatment options including drug detention facilities, short (i.e., 21-day) and long-term (i.e., 6 months) inpatient treatment, community-based treatment, group-based outpatient treatment, and prison-based treatment. Three studies (33%) reported no significant impacts of compulsory treatment compared with control interventions. Two studies (22%) found equivocal results but did not compare against a control condition. Two studies (22%) observed negative impacts of compulsory treatment on criminal recidivism. Two studies (22%) observed positive impacts of compulsory inpatient treatment on criminal recidivism and drug use. There is limited scientific literature evaluating compulsory drug treatment. Evidence does not, on the whole, suggest improved outcomes related to compulsory treatment approaches, with some studies suggesting potential harms.

    In heterogeneous treatment effect models with endogeneity, the identification of the local average treatment effect (LATE) typically relies on an instrument that satisfies two conditions: (i) joint independence of the potential post-instrument variables and the instrument and (ii) monotonicity...... of the treatment in the instrument, see Imbens and Angrist (1994). We show that identification is still feasible when replacing monotonicity by a strictly weaker local monotonicity condition. We demonstrate that the latter allows identifying the LATEs on the (i) compliers (whose treatment reacts to the instrument...

    A proper surface treatment, such as O2 plasma, helps to improve particle removal efficiency (PRE) because of the formation of hydrogen bonding between particles, water and the mask surface after treatment. The effectiveness of surface treatments cannot be determined only by the static wettability after processes. More key indexes should be considered. In this paper, we report our findings on the relationship between surface treatments on photomasks and the resulting wettability. In addition, added defects after the treatment and the cleaning process were inspected with a 193- nm KLA inspector on 193-nm immersion and EUV photomasks, which consist of SiO2, MoSi, Cr, Ta-based absorber and Ru. Based on our work, three indexes can be built for determining the effectiveness of surface treatments. The first is to check whether the surface becomes super-hydrophilic after treatment. The second is to determine the efficiency of surface treatments on enhancing wettability. The last is to quantify the added watermark count after the surface treatment and the cleaning process. With a proper surface treatment, watermarks can be greatly eased. These three indexes can quickly determine possible effective methods for treating the surfaces of different materials.

    2009-01-01

    Full Text Available Introduction. Sagittal mandible deficiency is the most common cause of skeletal Class II malocclusion. Treatment objective is to stimulate sagittal mandible growth. Fixed functional Herbst appliance use is beneficial for shortening the time required for treatment and does not depend on patient compliance. Case outline. A 13-year-old girl was referred to the Clinic of Orthodontics, School of Dentistry in Belgrade following previous unsuccessful treatment of her skeletal Class II malocclusion using an activator. The patient's poor cooperation had led to failure of the treatment. Patient was subjected to the Herbst treatment for 6 months followed by fixed appliance for another 8 months. Lateral cephalograms before and after the treatment was performed. The remodelation of condylar and fossal articulation was assessed by superimposition of pre- and post-treatment temporomandibular joint tomograms. The promotion of oral hygiene and fluoride use was performed because orthodontic treatment carries a high caries risk and risk for periodontal disease. Skeletal and dental changes were observed after treatment (correction [Max+Mand]: molar relation 7 mm, overjet 8 mm, skeletal relation 5 mm, molars 2 mm, incisors 3 mm. Combination of Herbst and fixed appliances was effective in the treatment of dental and skeletal irregularities for a short period of time. Conclusion . In the retention period, 14 months after treatment, occlusal stability exists. Follow-up care in oral prevention is based on regular recalls at the dental office and supervision at home by the parents.

  13. Effective physical treatment for chronic low back pain.

    Science.gov (United States)

    Maher, C G

    2004-01-01

    It is now feasible to adopt an evidence-based approach when providing physical treatment for patients with chronic LBP. A summary of the efficacy of a range of physical treatments is provided in Table 1. The evidence-based primary care options are exercise, laser, massage, and spinal manipulation; however, the latter three have small or transient effects that limit their value as therapies for chronic LBP. In contrast, exercise produces large reductions in pain and disability, a feature that suggests that exercise should play a major role in the management of chronic LBP. Physical treatments, such as acupuncture, backschool, hydrotherapy, lumbar supports, magnets, TENS, traction, ultrasound, Pilates therapy, Feldenkrais therapy, Alexander technique, and craniosacral therapy are either of unknown value or ineffective and so should not be considered. Outside of primary care, multidisciplinary treatment or functional restoration is effective; however, the high cost probably means that these programs should be reserved for patients who do not respond to cheaper treatment options for chronic LBP. Although there are now effective treatment options for chronic LBP, it needs to be acknowledged that the problem of chronic LBP is far from solved. Though treatments can provide marked improvements in the patient's condition, the available evidence suggests that the typical chronic LBP patient is left with some residual pain and disability. Developing new, more powerful treatments and refining the current group of known effective treatments is the challenge for the future.

    Full Text Available Objective : The purpose of this study is to estimate the effects of spiral taping treatment on low back pain. Methods : 420 low back pain patients were treated with spiral taping or spiral taping plus herbal medicine, and no other treatments such as acupuncture, herbal acupuncture, and chiropractic therapy were added. We evaluated the improvement by physical examination and pain. Results : 364 patients felt no pain or inconvenience of daily life and 43 patients showed improvement of pain or symptom after 1 month of treatment. 13 patients showed same pain with before treatment. Conclusions : These results suggest spiral taping treatments contribute to the improvement of low back pain. Further study is needed for the confirmation of this effect of spiral taping treatments on low back pain.

    The objective of this study was to determine the efficacy of percutaneous radiofrequency (RF) treatment of the trigeminal ganglion for treating patients with trigeminal neuralgia, to determine which patients have a long-term benefit, and to evaluate the effect of RF parameters. A retrospective study in 28 consecutive patients in combination with a follow-up questionnaire (n = 26, 93% response). An initial treatment effect of 89% was observed, 60% sustained at 12-month follow-up. Major side effects were hypesthesia (56%), dry eye (20%), and masseter muscle weakness (12%). A lower sensory stimulation threshold during treatment was associated with better patient satisfaction (P = 0.016), improved pain relief (P = 0.039), and trended toward more hypesthesia (P = 0.077). This low-volume study reported treatment effects in an older population that were similar to previous studies. Only a higher incidence of hypesthesia was detected by long-term follow-up. This study supported the high efficiency of RF treatment, but there was a high level of side effects. Most notable, low sensory stimulation was associated with increased hypesthesia, whereas higher stimulation levels yielded less effectiveness. Further investigation of an optimal sensory stimulation range for percutaneous RF treatment of the trigeminal ganglion was found to be warranted. © 2013 World Institute of Pain.

    Enhancing the cutting tool life is important and economic factor to reduce the tooling as well as manufacturing cost. The tool life is improved considerably by 92 % after cryogenic treatment. The cryogenic treatment is a one-time permanent, sub-zero heat treatment that entirely changes cross-section of cutting tool. The cryogenic treatment is carried out with deep freezing of cutting tool materials to enhance physical and mechanical properties. The cryogenic treatment improves mechanical such as hardness, toughness and tribological properties such as wear resistance, coefficient of friction, surface finish, dimensional stability and stress relief. The deep cryogenic treatment is the most beneficial treatment applied on cutting tools. The cryogenic treatment is the most advanced heat treatment and popular to improve performance of the cutting tool. The optimization of cryogenic treatment variables is necessary to improve tool life. This study reviews the effects of cryogenic treatment on microstructure, tribological properties of tool steels and machining applications of cutting tool by investigating the surface and performing the surface characterization test like SEM. The economy of cutting tool can be achieved by deep cryogenic treatment.

    The authors conducted a systematic review of the literature to determine the treatment effects of the Invisalign orthodontic system (Align Technology), Santa Clara, Calif.). The authors reviewed clinical trials that assessed Invisalign's treatment effects in nongrowing patients. They did not consider trials involving surgical or other simultaneous fixed or removable orthodontic treatment interventions. The authors searched electronic databases (PubMed, MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, Evidence Based Medicine Reviews, EMBASE Excerpta Medica, Thomsen's ISI Web of Science and LILACS) with the help of a senior health sciences librarian. They used "Invisalign" as the sole search term, and 22 documents appeared in the combined search. Thereafter, they used "clinical trials," "humans" and "Invisalign treatment effects" as abstract selection criteria. Only two published articles met these inclusion criteria, though after reading the actual articles, the authors determined that they did not adequately evaluate Invisalign treatment effects. Both articles identified methodological issues. The inadequately designed studies the authors found represented only a lower level of evidence (level II). Therefore, the authors found that no strong conclusions could be made regarding the treatment effects of Invisalign appliances. Future prospective randomized clinical trials are required to support, with sound scientific evidence, the claims about Invisalign's treatment effects. Clinicians will have to rely on their Invisalign clinical experience, the opinions of experts and the limited published evidence when using Invisalign appliances.

    Full Text Available Traditional Chinese Medicine (TCM, as a complex medical science which reflects philosophical principles and embodies large dialectical thought, is used to place the human body into a large system for observation. Acupuncture as a vital part of TCM, has been practiced to treat various diseases and symptoms. However, acupuncture is also facing severe challenges resulted from insufficient modern scientific research. Nowadays, the holistic effects of acupuncture can be researched by some modern approaches, such as the systems biology and fMRI technique. It is believed that having a better understand will greatly promote acupuncture research and be beneficial to scientization and modernization of acupuncture.

    The costs and water quality impacts of two regional configurations of municipal wastewater treatment plants in Northeastern Illinois are compared. In one configuration, several small treatment plants are consolidated into a smaller number of regional facilities. In the other, the smaller plants continue to operate. Costs for modifying the plants to obtain various levels of pollutant removal are estimated using a simulation model that considers the type of equipment existing at the plants and the costs of modifying that equipment to obtain a range of effluent levels for various pollutants. A dynamic water-quality/hydrology simulation model is used to determine the water quality effects of the various treatment technologies and pollutant levels. Cost and water quality data are combined and the cost-effectiveness of the two treatment configurations is compared. The regionalized treatment-plant configuration is found to be the more cost-effective.

    The purpose of Study 1 was to examine the relative efficacy of evidence-based treatments (EBTs) when compared to treatment-as-usual (TAU) for adults diagnosed with a personality disorder (PD). The purpose of Study 2 was to investigate the strength of the differences between bona fide psychotherapeutic treatments for PDs. Two separate computerized searches were conducted of: (a) studies that directly compared an EBT with a TAU for treatment of PDs, or (b) studies that compared at least two bona fide treatments for PDs. Meta-analytic methods were used to estimate the effectiveness of the treatments when compared to one another and to model how various confounding variables impacted the results of this comparative research. A total of 30 studies (Study 1; N=1662) were included in the meta-analysis comparing EBTs to TAU. A total of 12 studies (Study 2; N=723) were included in the meta-analysis comparing bona fide treatments. Study 1 found that EBTs were superior to TAU, although the TAU conditions were not comparable in many respects (e.g., not psychotherapy, lacking supervision, lacking training, etc.) to the EBT and there was significant heterogeneity in the effects. Study 2 found that some bona fide treatments were superior to others. © 2013.

    Background HIV-HCV coinfection produces high morbi-mortality. Direct-acting antivirals (DAAs) have shown high efficacy, although special attention should be paid to the risk of drug interactions. However, due to the lack of representativeness of coinfected patients in clinical trials, it is important to know real-world results. Objective To evaluate DAA treatment effectiveness in coinfected patients. We also analyse safety profile of DAA treatment and drug interactions between HCV and HIV therapy. Setting Descriptive study carried in a tertiary hospital of Spain Method HIV-HCV coinfected patients treated with DAAs between November 2014 and June 2016 were included. Main outcome measure Efficacy was measured in terms of sustained virologic response at week 12 after the end of therapy. Adverse events that led to treatment discontinuation were registered to evaluate the safety profile, and also drug interactions between DAAs and antiretroviral treatment were evaluated. Results Main HCV genotypes were 1a (34.9%) and 4 (24.5%). 51.9% were HCV previously treated, 54.7% had grade 4 liver fibrosis. SVR12 was reported in 90.6%. HCV treatment was well tolerated and there were no discontinuations because of adverse events. 30.2% of HIV treatments had to be modified before DAA treatment was started due to interactions, HIV suppression was not compromised. Conclusion DAA treatment in coinfected patients seems to be highly effective and secure. Evaluation of drug interactions must be a priority in order to maximize effectiveness and avoid toxicity.

    Evaluation of treatments for attention-deficit/hyperactivity disorder (ADHD) previously focused on symptom control, but attention has shifted to functional outcomes. The effect of different ADHD treatment periods and modalities (pharmacological, non-pharmacological, and combination) on long-term outcomes needs to be more comprehensively understood. A systematic search of 12 literature databases using Cochrane's guidelines yielded 403 English-language peer-reviewed, primary studies reporting long-term outcomes (≥2 years). We evaluated relative effects of treatment modalities and durations and effect sizes of outcomes reported as statistically significantly improved with treatment. The highest proportion of improved outcomes was reported with combination treatment (83% of outcomes). Among significantly improved outcomes, the largest effect sizes were found for combination treatment. The greatest improvements were associated with academic, self-esteem, or social function outcomes. A majority of outcomes improved regardless of age of treatment initiation (60%-75%) or treatment duration (62%-72%). Studies with short treatment duration had shorter follow-up times (mean 3.2 years total study length) than those with longer treatment durations (mean 7.1 years total study length). Studies with follow-up times ADHD improve with all treatment modalities, the combination of pharmacological and non-pharmacological treatment was most consistently associated with improved long-term outcomes and large effect sizes. Older treatment initiation age or longer durations did not markedly affect proportion of improved outcomes reported, but measurement of outcomes long periods after treatment cessation may attenuate results.

    The goal of this paper is to discuss experimental design options available for establishing the effects of treatment in studies that aim to examine the neural mechanisms associated with treatment-induced language recovery in aphasia, using functional magnetic resonance imaging (fMRI). We present both group and single-subject experimental or case-series design options for doing this and address advantages and disadvantages of each. We also discuss general components of and requirements for treatment research studies, including operational definitions of variables, criteria for defining behavioral change and treatment efficacy, and reliability of measurement. Important considerations that are unique to neuroimaging-based treatment research are addressed, pertaining to the relation between the selected treatment approach and anticipated changes in language processes/functions and how such changes are hypothesized to map onto the brain.

    Wood is a natural fiber reinforced composite. It structurally resembles bone tissue to some extent. Specially heat-treated birch wood has been used as a model material for further development of synthetic fiber reinforced composites (FRC) for medical and dental use. In previous studies it has been shown, that heat treatment has a positive effect on the osteoconductivity of an implanted wood. In this study the effects of two different heat treatment temperatures (140 and 200 degrees C) on wood were studied in vitro. Untreated wood was used as a control material. Heat treatment induced biomechanical changes were studied with flexural and compressive tests on dry birch wood as well as on wood after 63 days of simulated body fluid (SBF) immersion. Dimensional changes, SBF sorption and hydroxylapatite type mineral formation were also assessed. The results showed that SBF immersion decreases the biomechanical performance of wood and that the heat treatment diminishes the effect of SBF immersion on biomechanical properties. With scanning electron microscopy and energy dispersive X-ray analysis it was shown that hydroxylapatite type mineral precipitation formed on the 200 degrees C heat-treated wood. An increased weight gain of the same material during SBF immersion supported this finding. The results of this study give more detailed insight of the biologically relevant changes that heat treatment induces in wood material. Furthermore the findings in this study are in line with previous in vivo studies.

    Although chronic ethanol treatment is known to impair learning and memory, humans commonly consume a range of alcoholic beverages. However, the specific effects of some alcoholic beverages on behavioral performance are largely unknown. The present study compared the effects of a range of alcoholic beverages (plain ethanol solution, red wine, sake and whiskey; with a matched alcohol concentration of 10%) on learning and memory. 6-week-old C57BL6J mice were orally administered alcohol for 7 weeks. The results revealed that red wine treatment exhibited a trend toward improvement of spatial memory and advanced extinction of fear memory. Additionally, red wine treatment significantly increased mRNA levels of brain-derived neurotrophic factor (BDNF) and N-methyl-D-aspartate (NMDA) receptors in mice hippocampus. These results support previous reports that red wine has beneficial effects.

    The aim of the study was to evaluate the effects of an intensive rehabilitation programme on thyroid metabolism, the relationship between disability and thyroid hormone level, and the occurrence of nonthyroidal illness syndrome (NTIS) before and after rehabilitation. This was a clinical prospective study. Orthopaedic surgery patients (n = 82) were classified into two groups: patients in whom early active mobilization and walking were possible (walking group, WG, n = 45), and patients in whom these were not recommended (nonwalking group, NWG, n = 37). Levels of free T3 (fT3), fT4, TSH and rT3 were measured before and after surgery, and then at 1, 3, 7, 14 and 30 days from the beginning of rehabilitation. Personal, nutritional and clinical data were acquired for all patients. The Barthel Index (BI) was used to assess disability before and after rehabilitation. Immediately after surgery, both groups of patients showed a significant decrease in mean fT3 concentrations and a significant increase in rT3; mean fT4 values decreased significantly only in NWG patients. Once rehabilitation had been completed, fT3 and rT3 levels returned to baseline values in WG patients. In NWG patients mean fT3 and fT4 levels continued to decrease significantly and rT3 values remained significantly high until the end of rehabilitation. NTIS occurred in 38% of the NWG patients. No significant changes in TSH levels were observed in either group. Finally, we observed a direct correlation between fT3 levels and the BI in WG patients. Our data suggest that early patient mobilization and physical activity during an active and intensive rehabilitation programme induce recovery of thyroid function and avoid occurrence of NTIS.

    2016-10-01

    Dysphagia or swallowing difficulties have been reported to be a concern in adults with multiple sclerosis (MS). This problem can result in several complications including aspiration pneumonia, reduced quality of life and an increase in mortality rate. No previous systematic reviews on treatment effects for dysphagia in MS have been published. The main objective of this study is to summarise and qualitatively analyse published studies on treatment effects for dysphagia in MS. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were applied to conduct a systematic search of seven databases, using relevant key words, and subsequent analysis of the identified studies. The studies were required to meet all three inclusion criteria of including a statement on intention to treat, or measure the effects of treatment for dysphagia in adults with MS and data on treatment outcomes for at least one adult diagnosed with MS. Retained studies were evaluated by two independent reviewers using a critical appraisal tool. This study has not been registered. A total of 563 studies were identified from the database searches. After screening and assessment of full articles for eligibility, five studies were included in the review. Three examined electrical stimulation and two examined the use of botulinum toxin. One study testing electrical stimulation was a randomised controlled trial, two were well-designed case series and two were case series lacking experimental control. All studies reported some positive effects on dysphagia; however, treatments that involved the use of electrical stimulation showed larger effect sizes. There is a paucity of evidence to guide treatment of dysphagia in MS, with only electrical stimulation and botulinum toxin treatment represented in the literature search conducted here. While both treatments show initial promise for reducing the swallowing impairment, they require further research using well-controlled experimental

    In this work, an oxygen plasma treatment was used to improve the memory effect of nonvolatile W nanocrystal memory, including memory window, retention and endurance. To investigate the role of the oxygen plasma treatment in charge storage characteristics, the X-ray photon-emission spectra (XPS) were performed to analyze the variation of chemical composition for W nanocrystal embedded oxide both with and without the oxygen plasma treatment. In addition, the transmission electron microscopy (TEM) analyses were also used to identify the microstructure in the thin film and the size and density of W nanocrystals. The device with the oxygen plasma treatment shows a significant improvement of charge storage effect, because the oxygen plasma treatment enhanced the quality of silicon oxide surrounding the W nanocrystals. Therefore, the data retention and endurance characteristics were also improved by the passivation.

    In this work, an oxygen plasma treatment was used to improve the memory effect of nonvolatile W nanocrystal memory, including memory window, retention and endurance. To investigate the role of the oxygen plasma treatment in charge storage characteristics, the X-ray photon-emission spectra (XPS) were performed to analyze the variation of chemical composition for W nanocrystal embedded oxide both with and without the oxygen plasma treatment. In addition, the transmission electron microscopy (TEM) analyses were also used to identify the microstructure in the thin film and the size and density of W nanocrystals. The device with the oxygen plasma treatment shows a significant improvement of charge storage effect, because the oxygen plasma treatment enhanced the quality of silicon oxide surrounding the W nanocrystals. Therefore, the data retention and endurance characteristics were also improved by the passivation.

    Treatment and quarantine are efforts to cure as well as to overcome the spread of diseases including measles. The spread of measles can be expressed by mathematical modelling in the form of nonlinear dynamical systems. In this study was conducted on the spread of measles by considering the effect of treatment and quarantine on the infected individuals. By using the basic reproduction number of the model, can be analyzed the effects of treatment and quarantine to reduce the spread of measles. Basic reproduction number of models is monotonically descreasing as treatment and quarantine increasing. Numerical simulations conducted on the analysis of the results. The results showed that treatment and quarantine was given to infected individuals who were infectious has a major influence to eliminate measles from the system.

    In order to develop a water treatment programme following points must be kept in mind: Effectiveness to achieve desired water quality objectives; Compliance with regulatory requirements; Cost minimization; Safety; Easy operation and protection to equipments. Heavy Water Plant (Manuguru) laboratory has developed treatment programs to treat raw water and cooling water which satisfy the above requirements and has been in use for last several years successfully without any problem. These treatment programs have been given to other plants in Heavy Water Board for implementation. This paper describes the chemistry of the treatment program and cost minimization achieved. Further these treatments have helped the plant in achieving ΦZero Discharge and indirectly reduced the production cost. The chemistry parameters are monitored regularly to ascertain the effectiveness of these treatments. The areas where significant benefits derived are raw water treatment using polyelectrolyte instead of inorganic coagulant (alum), change over of regenerant of cation exchangers from hydrochloric acid to sulfuric acid and development of in-house cooling water treatment formulation. The advantages and cost effectiveness of these treatments are discussed in detail. Further these treatments helped the plant in achieving Zero discharge and indirectly reduced production cost of heavy water. The dosage of 3 ppm of polyelectrolyte can replace 90 ppm alum at turbidity level of 300 NTU of raw water which has resulted in cost saving of Rs. 15 - 20 Lakhs in a year besides other advantages. The changeover of regenerant from HCl to H 2 SO 4 will result in cost saving of at least Rs. 1.4 Crore a year along with other advantages. The change over of proprietary formulation to in-house formulation in cooling water treatment has resulted a saving about Rs. 11 Lakhs a year. To achieve the above objectives in a sustainable way the performance results are being monitored (author)

    To evaluate what effects treatments of sleep-disordered breathing have on snoring and sleepiness: snoring surgery including osteotomies, mandibular advancement device (MAD), and continuous positive airway pressure (CPAP). Single-institution prospective comparative effectiveness trial. University-affiliated secondary care teaching hospital. We prospectively studied 224 patients presenting with snoring at our department. All patients underwent detailed evaluation, including symptom questionnaires, clinical examination, polysomnography, and drug-induced sleep endoscopy. Based on these results, a treatment was proposed after multidisciplinary consultation. Treatment was evaluated through 4 questionnaires before treatment and 6 weeks and 6 months after. Treatment success was defined as a global snoring visual analog scale score ≤3 at 6 months. A total of 195 patients complied with full workup and were proposed treatment. The mean age was 46 ± 11 years; the mean body mass index, 27 ± 4; and the median apnea-hypopnea index, 10.0 (interquartile range, 4.7-20.1). After discussion, 116 (59.5%) patients agreed to start treatment (46%, surgery; 26% MAD; 28% CPAP). All symptom scores, including Epworth Sleepiness Scale, decreased significantly for all treatments at 6 weeks and 6 months. Treatment was successful in 67% of the surgery patients, 67% of the MAD group, and 76% of the CPAP group. Only 6.7% reported an unchanged snoring score in the surgery group, compared with 13.6% in the MAD group and 9.6 % in the CPAP group. Multidisciplinary agreed-on treatment of snoring is effective across the proposed treatments. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    Localised scleroderma is an uncommon connective tissue disease of multifactorial aetiology occurring in the paediatric and adult population. It is relatively difficult to conduct any research on the subject of this disease entity treatment due to the low number of patients suffering from morphea, a tendency of the disease to remit spontaneously, and not yet well recognised aetiology. Hence, there has been developed no causal treatment of well-proven effectiveness, and schedules of symptomatic therapy are not yet clearly determined. The paper depicts most widely used topical treatment methods in morphea therapy, which due to minor risk of systemic adverse effects seem to be a beneficial therapeutic alternative. The main aim of this article was to analyse different topical treatment options used in localised scleroderma therapy and to indicate the most appropriate, safe, and effective one.

    What we believe we will experience from a treatment--our expectation--has a substantial impact on what we actually experience. Expectation has been established as a key process behind the placebo effect. Studies in both laboratory and clinical settings consistently show that when people ingest a pharmacologically inert substance (placebo) but believe that it is an active substance, they experience both the subjective sensations and physiologic effects expected from that active substance. Expectation has an important place in the response to "real" treatment as well. This paper provides an overview of the data which point to the role of expectation in both the placebo effect and the response to treatment. These data suggest that clinicians might enhance the benefit of all treatments by promoting patients' positive expectations.

Many patients have benefited from the advent of second-generation antipsychotics, which can offer good symptomatic control with reduced incidence of extrapyramidal symptoms, although with higher risk of metabolic side effects. It is unsurprising that accounts as to whether first- and second-generation antipsychotics differ in their efficacy vary, since treatment effectiveness is a broad notion and difficult to define. Objectives: Numerous factors may be used to gauge treatment effectiveness and, while it has largely been defined in terms of improvements in four domains (symptoms of disease, treatment burden, disease burden, and health and wellness, the real-world clinical utility of this consensus is unclear. Therefore, this article aims to provide a framework that can aid psychiatrists in making assessments about treatment effectiveness. Methods and results: A panel of 12 psychiatrists and psychopharmacologists convened to develop and propose an accessible and globally-applicable framework for assessing the effectiveness of antipsychotic treatments in patients with schizophrenia

    When the food poisoning bacteria Salmonella enteritidis and S. typhimurium were treated with radiation (cobalt-60 γ-rays) and heat (10 minutes at 45 0 C or 50 0 C), their sterilizing effect was revealed differently depending on the order of treatments. Post-irradiation heating showed a synergistic effect whereas pre-irradiation heating revealed the opposite effect and the effects differed slightly with heating temperature. (author)

  2. Measuring the effect of fuel treatments on forest carbon using landscape risk analysis

    Full Text Available Wildfire simulation modelling was used to examine whether fuel reduction treatments can potentially reduce future wildfire emissions and provide carbon benefits. In contrast to previous reports, the current study modelled landscape scale effects of fuel treatments on fire spread and intensity, and used a probabilistic framework to quantify wildfire effects on carbon pools to account for stochastic wildfire occurrence. The study area was a 68 474 ha watershed located on the Fremont-Winema National Forest in southeastern Oregon, USA. Fuel reduction treatments were simulated on 10% of the watershed (19% of federal forestland. We simulated 30 000 wildfires with random ignition locations under both treated and untreated landscapes to estimate the change in burn probability by flame length class resulting from the treatments. Carbon loss functions were then calculated with the Forest Vegetation Simulator for each stand in the study area to quantify change in carbon as a function of flame length. We then calculated the expected change in carbon from a random ignition and wildfire as the sum of the product of the carbon loss and the burn probabilities by flame length class. The expected carbon difference between the non-treatment and treatment scenarios was then calculated to quantify the effect of fuel treatments. Overall, the results show that the carbon loss from implementing fuel reduction treatments exceeded the expected carbon benefit associated with lowered burn probabilities and reduced fire severity on the treated landscape. Thus, fuel management activities resulted in an expected net loss of carbon immediately after treatment. However, the findings represent a point in time estimate (wildfire immediately after treatments, and a temporal analysis with a probabilistic framework used here is needed to model carbon dynamics over the life cycle of the fuel treatments. Of particular importance is the long-term balance between emissions from the

    Prenatal methylazoxymethanol acetate (MAM) treatment has been shown to induce morphological abnormalities in cortical areas of the offspring. Based on the neuroanatomical and behavioural abnormalities, this treatment has been suggested as a useful animal model for schizophrenia. In a previous study (Jongen-Relo AL, Leng A, Luber M, Pothuizen HHJ, Weber L, Feldon J. The prenatal methylazoxymethanol acetate treatment: a neurodevelopmental animal model for schizophrenia? Behav Brain Res 2004;149:159-81) we have studied MAM-treated animals in a series of behavioural tests related to schizophrenia, such as latent inhibition and pre-pulse inhibition of the acoustic startle response to establish the validity of prenatal MAM treatment (20mg/kg i.p. on gestational days 9-15; MAM 9-MAM 15). We found that, apart from a marginal effect of increased activity in the open field, the MAM treatment on gestational day 15 was behaviourally ineffective. Here, we extended our previous study to a water maze experiment conducted in the same batch of animals as presented previously (MAM 12-MAM 15). MAM-treated animals showed similar water maze performance compared with control animals during the acquisition phase and the probe tests. However, during the reversal phase, MAM 15 animals showed impaired acquisition of the new platform location. This might indicate some cognitive deficits in MAM 15 animals in terms of working memory or behavioural flexibility. However, in combination with the lack of behavioural abnormalities of MAM 12-MAM 15 animals in several other tests related to schizophrenia in the previously reported study, the use of MAM treatment (MAM 12-MAM 15) as a valid model for schizophrenia still remains debatable.

    Full Text Available Introduction The rate of operative birth by Caesarean section is constantly rising. In Kazakhstan, it reaches 27 per cent. Research data confirm that the percentage of successful vaginal births after previous Caesarean section is 50–70 per cent. How safe the induction of vaginal birth after Caesarean (VBAC remains unclear. Methodology The studied techniques of labour induction were amniotomy of the foetal bladder with the vulsellum ramus, intravaginal administration of E1 prostaglandin (Misoprostol, and intravenous infusion of Oxytocin-Richter. The assessment of rediness of parturient canals was conducted by Bishop’s score; the labour course was assessed by a partogram. The effectiveness of labour induction techniques was assessed by the number of administered doses, the time of onset of regular labour, the course of labour and the postpartum period and the presence of complications, and the course of the early neonatal period, which implied the assessment of the child’s condition, described in the newborn development record. The foetus was assessed by medical ultrasound and antenatal and intranatal cardiotocography (CTG. Obtained results were analysed with SAS statistical processing software. Results The overall percentage of successful births with intravaginal administration of Misoprostol was 93 per cent (83 of cases. This percentage was higher than in the amniotomy group (relative risk (RR 11.7 and was similar to the oxytocin group (RR 0.83. Amniotomy was effective in 54 per cent (39 of cases, when it induced regular labour. Intravenous oxytocin infusion was effective in 94 per cent (89 of cases. This percentage was higher than that with amniotomy (RR 12.5. Conclusions The success of vaginal delivery after previous Caesarean section can be achieved in almost 70 per cent of cases. At that, labour induction does not decrease this indicator and remains within population boundaries.

    Full Text Available Background: Whereas the effects of various socio-demographic determinants on a woman's risk of having an abortion are relatively well-documented, less attention has been given to the effect of previous abortions and births. Objective: To study the effect of previous abortions and births on Danish women's risk of an abortion, in addition to a number of demographic and personal characteristics. Data and methods: From the Fertility of Women and Couples Dataset we obtained data on the number of live births and induced abortions by year (1981-2001, age (16-39, county of residence and marital status. Logistic regression analysis was used to estimate the influence of the explanatory variables on the probability of having an abortion in a relevant year. Main findings and conclusion: A woman's risk of having an abortion increases with the number of previous births and previous abortions. Some interactions were was found in the way a woman's risk of abortion varies with calendar year, age and parity. The risk of an abortion for women with no children decreases while the risk of an abortion for women with children increases over time. Furthermore, the risk of an abortion decreases with age, but relatively more so for women with children compared to childless women. Trends for teenagers are discussed in a separate section.

  7. Psychiatrist effects in the psychopharmacological treatment of depression.

    The National Institutes of Mental Health's (NIMH) 1985 Treatment of Depression Collaborative Research Program (TDCRP) reported that imipramine hydrochloride with clinical management (IMI-CM) was significantly more beneficial than placebo with clinical management (PLA-CM) for individuals undergoing treatment for depression. Unfortunately, in analyzing the NIMH TDCRP data, researchers ignored the potential effect that psychiatrists have on patient outcomes, thereby assuming that psychiatrists are equally effective. However, this assumption has yet to be supported empirically. Therefore, the purpose of the current study is to examine psychiatrist effects in the NIMH TDCRP study and to compare the variation among psychiatrists to the variation between treatments. Data from 112 patients [IMI-CM (n = 57, 9 psychiatrists); PLA-CM (n = 55, 9 psychiatrists)] from the NIMH TDCRP study were reanalyzed using a multi-level model. The proportion of variance in the BDI scores due to medication was 3.4% (p < .05), while the proportion of variance in BDI scores due to psychiatrists was 9.1% (p < .05). The proportion of variance in the HAM-D scores due to medication was 5.9% (p < .05), while the proportion of variance in HAM-D scores due to psychiatrist was 6.7% (p = .053). Therefore, the psychiatrist effects were greater than the treatment effects. In this study, both psychiatrists and treatments contributed to outcomes in the treatment of depression. However, given that psychiatrists were responsible for more of the variance in outcomes it can be concluded that effective treatment psychiatrists can, in fact, augment the effects of the active ingredients of anti-depressant medication as well as placebo.

    Endocrine disruption (ED) effects due to pulp and paper mill effluents extracts involving different industrial procedures and effluent treatments (nontreated, primary, and secondary treated) were evaluated using immature triploid rainbow trout in a pulse-exposure toxicity experiment. The protocol involved the use of intraperitoneal injection of mill extracts (solid-phase extraction [SPE]) corrected for individual fish weight and included several laboratory standards (steroidal hormones and phytosterols). Biological endpoints at two different levels of biological organization were analyzed (molecular and individual organism). Results indicated that nonsignificant changes were observed in the individual physiological indices represented by condition factor, liver somatic index, and gonad somatic index during the experiment. Significant induction of liver ethoxyresorufin-O-deethylase activity was observed between different effluent treatments and experimental controls. Significant endocrine-disrupting effects at the reproductive level were observed in all effluent treatments involving significant increments in plasma vitellogenin (VTG) levels. Fish exposed to untreated effluent extracts had significantly higher VTG levels compared to fish exposed to primary and secondary treatment effluent extracts, indicating a decrease of the estrogenic effect due to the effluent treatment. The present study has shown that for the Chilean pulp and paper mill SPE extracts evaluated, an endocrine disruption effect was induced in immature triploid rainbow, reaffirming the significant estrogenic effects demonstrated previously in laboratory and field experiments.

    Yeast hydrolysate supplements promote maturation of many tephritid flies targeted for control using the sterile insect technique (SIT), including Queensland fruit fly (Bactrocera tryoni; 'Q-fly'). Recently, application of the juvenile hormone analogue methoprene has been demonstrated to further promote maturation in some species. We here investigate the separate and combined effects of yeast hydrolysate and methoprene treatment on sexual maturation of sterile male and female Q-flies. Two methods of applying methoprene solution were used; topical application to adults and dipping of pupae. Consistent with previous studies, access to yeast hydrolysate greatly increased maturation of both male and female Q-flies. Maturation was further promoted by methoprene treatment, with similar effects evident for males and females and for both application methods. For flies provided access to yeast hydrolysate supplements, methoprene treatment advanced maturation by approximately 2days. No effects of diet or methoprene treatment were found on timing of copulation or copula duration. Countering the positive effects on sexual maturation, dipping of pupae in methoprene/acetone solution did diminish emergence rates and flight ability indices, and increased rates of wing deformity. Promising results of the present study encourage further investigation of treatment methods that maximise maturation while minimising detrimental effects on other aspects of fly quality.

    Cannabis extracts have a wide therapeutic potential but in many countries they have not been approved for treatment in children so far. We conducted an open, uncontrolled, retrospective study on the administration of dronabinol to determine the value, efficacy, and safety of cannabis-based medicines in the treatment of refractory spasticity in pediatric palliative care. Sixteen children, adolescents and young adults having complex neurological conditions with spasticity (aged 1.3-26.6 years, median 12.7 years) were treated with dronabinol by our specialized pediatric palliative care team between 01.12.2010 and 30.04.2015 in a home-care setting. Therapeutic efficacy and side effects were closely monitored. Drops of the 2.5% oily tetrahydrocannabinol solution (dronabinol) were administered. A promising therapeutic effect was seen, mostly due to abolishment or marked improvement of severe, treatment resistant spasticity (n = 12). In two cases the effect could not be determined, two patients did not benefit. The median duration of treatment was 181 days (range 23-1429 days). Dosages to obtain a therapeutic effect varied from 0.08 to 1.0 mg/kg/d with a median of 0.33 mg/kg/d in patients with a documented therapeutic effect. When administered as an escalating dosage scheme, side effects were rare and only consisted in vomiting and restlessness (one patient each). No serious and enduring side effects occurred even in young children and/or over a longer period of time. In the majority of pediatric palliative patients the treatment with dronabinol showed promising effects in treatment resistant spasticity. Copyright © 2016 European Paediatric Neurology Society.

This requires knowledge of the type of radiation applied and when it was applied, additional harmful influences, exposure, differentiation in cases of ulcers between primary, cumulative, and combination effect, early radiation effects, and late radiation effects. Secondary factors leading possibly to necrosis may be: recidivation of the primary tumours, benign or malignant neoplasms, traumatic injuries such as injections, sampling, tight clothing, chemical factors like therapeuticals for local application, allergies, infections of the skin with bacteria or fungi, osteomyelitis, non-infections skin disease, and internal disease. A precondition for successful dermatological and surgical treatment are a careful review of the previous case history and exact diagnosis. Some clinical cases serve to illustrate the theoretical explanations and point out possibilities for surgical treatment. (TRV) [de

  1. Testing Overall and Subpopulation Treatment Effects with Measurement Errors.

    There is a growing interest in the discovery of important predictors from many potential biomarkers for therapeutic use. In particular, a biomarker has predictive value for treatment if the treatment is only effective for patients whose biomarker values exceed a certain threshold. However, biomarker expressions are often subject to measurement errors, which may blur the biomarker's predictive capability in patient classification and, as a consequence, may lead to inappropriate treatment decisions. By taking into account the measurement errors, we propose a new testing procedure for the overall and subpopulation treatment effects in the multiple testing framework. The proposed method bypasses the permutation or other resampling procedures that become computationally infeasible in the presence of measurement errors. We conduct simulation studies to examine the performance of the proposed method, and illustrate it with a data example.

    Amblyopia, defined as poor vision due to abnormal visual experience early in life, affects approximately three per cent of the population and carries a projected lifetime risk of visual loss of at least 1.2 per cent. The presence of amblyopia or its risk factors, mainly strabismus or refractive error, have been primary conditions targeted in childhood vision screenings. Continued support for such screenings requires evidence-based understanding of the prevalence and natural history of amblyopia and its predisposing conditions, and proof that treatment is effective in the long term with minimal negative impact on the patient and family. This review summarises recent research relevant to the clinical understanding of amblyopia, including prevalence data, risk factors, the functional impact of amblyopia and optimum treatment regimes and their justification from a vision and life skills perspective. Collectively, these studies indicate that treatment for amblyopia is effective in reducing the overall prevalence and severity of visual loss from amblyopia. Correction of refractive error alone has been shown to significantly reduce amblyopia and less frequent occlusion can be just as effective as more extensive occlusion. Occlusion or penalisation in amblyopia treatment can create negative changes in behaviour in children and impact on family life, and these factors should be considered in prescribing treatment, particularly because of their influence on compliance. Ongoing treatment trials are being undertaken to determine both the maximum age at which treatment of amblyopia can still be effective and the importance of near activities during occlusion. This review highlights the expansion of current knowledge regarding amblyopia and its treatment to help clinicians provide the best level of care for their amblyopic patients that current knowledge allows.

    Lithium has been used in psychiatry for over 60 years and is still one of the first-line treatments in bipolar disorder. It is also used as augmentation to antidepressants in treatment resistant depression. Age-dependent changes in lithium pharmacokinetics and pharmacodynamics may influence lithium use patterns in an ageing population. Multimorbidity and polypharmacy could make older patients more vulnerable to the adverse effects of lithium. The main objectives of this thesis were to study t...

    The aim of this study was to analyse the effect of heat treatment parameters on liquid whole egg (LWE) proteins by using ultraviolet-visible (UV-VIS) spectroscopy and capillary electrophoresis (CE). Heat treatment (at 60-68°C for 1-5min) was applied to LWE. Treated LWE was centrifuged and supernatant was taken for measurement of UV-VIS spectroscopy and CE. The change in UV absorbance showed loss of protein solubility depending on heat treatments parameters. Electropherograms of samples demonstrated the effect of treatment parameters on composition of LWE proteins. It was found that conalbumin and lysozyme were influenced by the treatment, while ovalbumin and ovomucoid were not affected. CE combined with principal component analysis (PCA) was used for classification of samples untreated or treated and treated at different treatment parameters. The results of the study revealed that the extent of heat treatment in LWE samples could be determined with PCA of the CE measurements. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The modified or "emotional" Stroop paradigm has been frequently employed in previous evaluations of information processing models of Posttraumatic Stress Disorder (PTSD) and other anxiety disorders. These studies have frequently documented an attentional bias to trauma-specific threatening stimuli in PTSD patients. However, the response of the Stroop color-naming interference effect to psychological treatment has yet to be tested in a trauma population. The present study evaluated the effects of three treatment conditions on the Stroop interference effect in motor vehicle accident (MVA) survivors with PTSD. Following treatment, participants were classified as either treatment responders or nonresponders. Participants named the color of three types of stimuli: MVA trauma-specific words, neutral words, and nonwords. Results showed that change in selective color-naming interference for trauma cues was unrelated to treatment response or modality at either posttreatment or follow-up. Findings cast doubt on the clinical utility of the modified Stroop test as a measure of treatment outcome in this population.

    Background GnRH agonist administration in the luteal phase has been suggested to beneficially affect the outcome of intracytoplasmic sperm injection (ICSI) and embryo transfer (ET) cycles. This blind randomized controlled study evaluates the effect of GnRH (Gonadotropine Releasing Hormone) agonist administration on ICSI outcome in GnRH antagonist ovarian stimulation protocol in women with 2 or more previous IVF/ICSI-ET failures. Methods One hundred IVF failure women who underwent ICSI cycles and stimulated with GnRH antagonist ovarian stimulation protocol, were included in the study. Women were randomly assigned to intervention (received a single dose injection of GnRH agonist (0.1 mg of Decapeptil) subcutaneously 6 days after oocyte retrieval) and control (did not receive GnRH agonist) groups. Implantation and clinical pregnancy rates were the primary outcome measures. Results Although the age of women, the number of embryos transferred in the current cycle and the quality of the transferred embryos were similar in the two groups, there was a significantly higher rate of implantation (Mann Whitney test, p = 0.041) and pregnancy (32.6% vs. 12.5%, p = 0.030, OR = 3.3, 95%CI, 1.08 to 10.4) in the intervention group. Conclusion Our results suggested that, in addition to routine luteal phase support using progesterone, administration of 0.1 mg of Decapeptil 6 days after oocyte retrieval in women with previous history of 2 or more IVF/ICSI failures led to a significant improvement in implantation and pregnancy rates after ICSI following ovarian stimulation with GnRH antagonist protocol.

    We investigated differential treatment effects on specific eating disorder (ED) indicators to enhance conclusions about treatment efficacy. Profile Analysis via Multidimensional Scaling, which identifies core profiles in a population and interprets person profiles with core profile information, was utilized to identify core profiles from a sample of 5,177 patients who were repeatedly measured with the ED inventory-2 at admission and at discharge. To assess differential treatment effects for individual ED indicators, we compared the core profiles at admission with those at discharge. Three core profiles were identified and labeled as High Body Dissatisfaction with Low Bulimia (Core Profile 1), High Interoceptive Awareness with Low Body Dissatisfaction (Core Profile 2), and High Ineffectiveness with Low Bulimia (Core Profile 3). Treatment had the greatest effects on Core Profile 2. The patients whose profile patterns were similar to that of Core Profiles 1 and 2 were positively related with weight gain. However, treatment was least on Core Profile 3, and the patients whose profile patterns were like that of Core Profile 3 were negatively related with weight gain. In conclusion, those patients who fit Core Profile 3 may benefit from different treatment modalities than those that are standard in inpatient settings. Copyright © 2017 John Wiley & Sons, Ltd.

    Eighty-six children were diagnosed with cancer in infancy, followed for at lest 5 years, and assessed for late effects of disease and therapy. One child subsequently died from respiratory failure and 3 died from second primary cancers. Another patient survived second primary cancers of the skin. The high frequency of new cancers (4 observed, 0.09 expected) was attributable to host susceptibility factors and treatment effects. Kyphoscoliosis was diagnosed in 44 patients, 40 of whom had received radiotherapy to the spine. Other patients had neurologic deficits, pulmonary fibrosis, hypoplastic breasts, bowel adhesions, thyroid nodules, musculoskeletal defects, and liver fibrosis associated with tumor therapy. Sequelae of cancer were more common after treatment in infancy than in later childhood. Improved treatments and knowledge of natural history can reduce adverse effects of therapy

    1975-01-01

    The ability of acoustic liners to reduce compressor noise inside and in front of an inlet was studied. An axial flow research compressor and a specially designed inlet were used inside an anechoic chamber. Acoustic and performance data were obtained for a range of inlet treatment locations and cavity depths to determine their effects on inlet noise over a range of blade passing frequencies. The greatest noise reductions in front of the inlet were obtained with acoustic treatment located close to the compressor and backed with the deepest cavities tested. Inside the inlet the maximum noise level reductions were obtained in the area of the treatment regardless of treatment location. No appreciable losses in compressor performance were measured.

    Full Text Available Evaluation of treatments for attention-deficit/hyperactivity disorder (ADHD previously focused on symptom control, but attention has shifted to functional outcomes. The effect of different ADHD treatment periods and modalities (pharmacological, non-pharmacological, and combination on long-term outcomes needs to be more comprehensively understood.A systematic search of 12 literature databases using Cochrane's guidelines yielded 403 English-language peer-reviewed, primary studies reporting long-term outcomes (≥2 years. We evaluated relative effects of treatment modalities and durations and effect sizes of outcomes reported as statistically significantly improved with treatment.The highest proportion of improved outcomes was reported with combination treatment (83% of outcomes. Among significantly improved outcomes, the largest effect sizes were found for combination treatment. The greatest improvements were associated with academic, self-esteem, or social function outcomes. A majority of outcomes improved regardless of age of treatment initiation (60%-75% or treatment duration (62%-72%. Studies with short treatment duration had shorter follow-up times (mean 3.2 years total study length than those with longer treatment durations (mean 7.1 years total study length. Studies with follow-up times <3 years reported benefit with treatment for 93% of outcomes, whereas those with follow-up times ≥3 years reported treatment benefit for 57% of outcomes. Post-hoc analysis indicated that this result was related to the measurement of outcomes at longer periods (3.2 versus 0.4 years after treatment cessation in studies with longer total study length.While the majority of long-term outcomes of ADHD improve with all treatment modalities, the combination of pharmacological and non-pharmacological treatment was most consistently associated with improved long-term outcomes and large effect sizes. Older treatment initiation age or longer durations did not markedly

    Full Text Available Background: Permethrin is the drug of choice for scabies with side effects such as erythema, pain, itching and prickling sensation. Whole-body (standard topical application of permethrin causes discomfort; thus, modified application of permethrin to the lesion only, followed with baths twice daily using soap was proposed. The objective of the study is to know the effectiveness of standard against lesion-only application of permethrin in scabies treatment.Methods: An experimental study was conducted in pesantren in East Jakarta and data was collected in May-July 2012. Diagnosis of scabies was made through anamnesis and skin examination. Subjects positive for scabies were divided into three groups: one standard method group (whole-body topical application and two modified groups (lesion-only application followed by the use of regular soap and antiseptic soap group. The three groups were evaluated weekly for three consecutive weeks. Data was processed using SPSS 20 and analyzed by Kruskal-Wallis test.Results: Total of 94 subjects was scabies positive (prevalence 50% but only 69 subjects were randomly picked to be analyzed. The cure rate at the end of week III of the standard method group was 95.7%, modified treatment followed by the use of regular soap was 91.3%, and modified treatment followed by the use of antiseptic soap was 78.3% (p = 0.163. The recurrence rate of standard treatment was 8.7%,  modified treatment followed by the use of regular soap was 13% and modified treatment followed by the use of antiseptic soap was 26.1% (p = 0.250.Conclusion: The standard scabies treatment was as effective as the modified scabies treatment.

    Three decades ago, John R Hampton announced the death of clinical freedom. Since then, evidence-based medicine has been the predominant paradigm in clinical research. By applying a population-based approach, the randomised controlled trial has become the cornerstone for demonstrating the overall effect of a treatment and for developing guidelines. The new patient-centred medicine movement is rediscovering the important implications of heterogeneity of treatment effects for clinical practice and that a better understanding of such variability can contribute to improve health outcomes for individual patients through practicing a science-based clinical freedom. © 2015 The Authors.

    PurposeTo evaluate the effect of previous transarterial iodized oil tissue marking (ITM) on technical parameters, three-dimensional (3D) computed tomographic (CT) rendering of the electroporation zone, and histopathology after CT-guided irreversible electroporation (IRE) in an acute porcine liver model as a potential strategy to improve IRE performance.MethodsAfter Ethics Committee approval was obtained, in five landrace pigs, two IREs of the right and left liver (RL and LL) were performed under CT guidance with identical electroporation parameters. Before IRE, transarterial marking of the LL was performed with iodized oil. Nonenhanced and contrast-enhanced CT examinations followed. One hour after IRE, animals were killed and livers collected. Mean resulting voltage and amperage during IRE were assessed. For 3D CT rendering of the electroporation zone, parameters for size and shape were analyzed. Quantitative data were compared by the Mann–Whitney test. Histopathological differences were assessed.ResultsMean resulting voltage and amperage were 2,545.3 ± 66.0 V and 26.1 ± 1.8 A for RL, and 2,537.3 ± 69.0 V and 27.7 ± 1.8 A for LL without significant differences. Short axis, volume, and sphericity index were 16.5 ± 4.4 mm, 8.6 ± 3.2 cm{sup 3}, and 1.7 ± 0.3 for RL, and 18.2 ± 3.4 mm, 9.8 ± 3.8 cm{sup 3}, and 1.7 ± 0.3 for LL without significant differences. For RL and LL, the electroporation zone consisted of severely widened hepatic sinusoids containing erythrocytes and showed homogeneous apoptosis. For LL, iodized oil could be detected in the center and at the rim of the electroporation zone.ConclusionThere is no adverse effect of previous ITM on technical parameters, 3D CT rendering of the electroporation zone, and histopathology after CT-guided IRE of the liver.

  17. Integrating fasciolosis control in the dry cow management: the effect of closantel treatment on milk production.

    Directory of Open Access Journals (Sweden)

    Johannes Charlier

    Full Text Available The liver fluke Fasciola hepatica is a parasite of ruminants with a worldwide distribution and an apparent increasing incidence in EU member states. Effective control in dairy cattle is hampered by the lack of flukicides with a zero-withdrawal time for milk, leaving the dry period as the only time that preventive treatment can be applied. Here, we present the results of a blinded, randomized and placebo-controlled trial on 11 dairy herds (402 animals exposed to F. hepatica to 1 assess the effect of closantel treatment at dry-off (or 80-42 days before calving in first-calving heifers on milk production parameters and 2 evaluate if a number of easy-to-use animal parameters is related to the milk production response after treatment. Closantel treatment resulted in a noticeable decrease of anti-F. hepatica antibody levels from 3-6 months after treatment onwards, a higher peak production (1.06 kg and a slightly higher persistence (9% of the lactation, resulting in a 305-day milk production increase of 303 kg. No effects of anthelmintic treatment were found on the average protein and fat content of the milk. Milk production responses after treatment were poor in meagre animals and clinically relevant higher milk production responses were observed in first-lactation animals and in cows with a high (0.3-0.5 optical density ratio (ODR, but not a very high (≥ 0.5 ODR F. hepatica ELISA result on a milk sample from the previous lactation. We conclude that in dairy herds exposed to F. hepatica, flukicide treatment at dry-off is a useful strategy to reduce levels of exposure and increase milk production in the subsequent lactation. Moreover, the results suggest that treatment approaches that only target selected animals within a herd can be developed based on easy-to-use parameters.

    Full Text Available Kristian Thorlund1, Edward Mills1,21Department of Clinical Epidemiology and Biostatistics, McMaster University, Hamilton, 2Faculty of Health Sciences, University of Ottawa, Ottawa, ON, CanadaBackground: Many medical interventions are administered in the form of treatment combinations involving two or more individual drugs (eg, drug A + drug B. When the individual drugs and drug combinations have been compared in a number of randomized clinical trials, it is possible to quantify the comparative effectiveness of all drugs simultaneously in a multiple treatment comparison (MTC meta-analysis. However, current MTC models ignore the dependence between drug combinations (eg, A + B and the individual drugs that are part of the combination. In particular, current models ignore the possibility that drug effects may be additive, ie, the property that the effect of A and B combined is equal to the sum of the individual effects of A and B. Current MTC models may thus be suboptimal for analyzing data including drug combinations when their effects are additive or approximately additive. However, the extent to which the additivity assumption can be violated before the conventional model becomes the more optimal approach is unknown. The objective of this study was to evaluate the comparative statistical performance of the conventional MTC model and the additive effects MTC model in MTC scenarios where additivity holds true, is mildly violated, or is strongly violated.Methods: We simulated MTC scenarios in which additivity held true, was mildly violated, or was strongly violated. For each scenario we simulated 500 MTC data sets and applied the conventional and additive effects MTC models in a Bayesian framework. Under each scenario we estimated the proportion of treatment effect estimates that were 20% larger than ‘the truth' (ie, % overestimates, the proportion that were 20% smaller than ‘the truth' (ie, % underestimates,The coverage of the 95% credible

  19. Fate and Effect of Dissolved Silicon within Wastewater Treatment Effluent.

    2017-07-05

    In large rivers, the ratios of silicon (Si)/nitrogen (N)/phosphorus (P) have changed dramatically as anthropogenic additions of N or P are not matched by Si. Wastewater effluent is a recognized source of N and P to coastal environments. Few previous studies, however, have examined the Si load of a large wastewater plant's effluent or the molar ratios of Si/N and Si/P in effluent. We examine the annual flux of dissolved silicon (DSi) carried by effluent from the second largest treatment plant by flow in the United States (Deer Island Treatment Plant, DITP, Boston, MA). We compare treatment plant nutrient fluxes to local urban river nutrient fluxes and trace the impact of the DITP DSi loading on receiving waters. Estimates (±95% confidence interval) of treated effluent (67 800 ± 1500 kmol DSi year -1 ) compared to untreated (69 500 kmol DSi year -1 ) indicate that the process of sewage treatment at DITP likely does not remove DSi. DITP effluent was Si-limited and this Si-limitation is reflected in the receiving waters (Massachusetts Bay). However, Si-limitation appears only in the area immediately surrounding the effluent discharge. We use these results to explain phytoplankton patterns in Massachusetts Bay and to provide the first estimate of DSi loading (3.6 Gmol SiO 2 year -1 ) from wastewater effluent across the US.

    2008-01-01

    Inflammation often plays a key role in the perpetuation of pain. Chronic inflammatory conditions (e.g. osteoarthritis, immune system dysfunction, micro-circulatory disease, painful neuritis, and even heart disease) have increased as baby boomers age. Medicine's current anti-inflammatory choices are NSAIDs and steroids; the value in promoting cure and side effect risks of these medications are unclear and controversial, especially considering individual patient variations. Electricity has continuously been a powerful tool in medicine for thousands of years. All medical professionals are, to some degree, aware of electrotherapy; those who directly use electricity for treatment know of its anti-inflammatory effects. Electronic signal treatment (EST), as an extension of presently available technology, may reasonably have even more anti-inflammatory effects. EST is a digitally produced alternating current sinusoidal electronic signal with associated harmonics to produce theoretically reasonable and/or scientifically documented physiological effects when applied to the human body. These signals are produced by advanced electronics not possible even 10 to 15 years ago. The potential long-lasting anti-inflammatory effects of some electrical currents are based on basic physical and biochemical facts listed in the text below, namely that of stimulating and signaling effective and long-lasting anti-inflammatory effects in nerve and muscle cells. The safety of electrotherapeutic treatments in general and EST in particular has been established through extensive clinical use. The principles of physics have been largely de-emphasized in modern medicine in favor of chemistry. These electrical treatments, a familiar application of physics, thus represent powerful and appropriate elements of physicians' pain care armamentaria in the clinic and possibly for prescription for use at home to improve overall patient care and maintenance of quality of life via low-risk and potentially

  1. Effect of Surface Treatment on the Properties of Wool Fabric

    Science.gov (United States)

    Kan, C. W.; Yuen, C. W. M.; Chan, C. K.; Lau, M. P.

    Wool fiber is commonly used in textile industry, however, it has some technical problems which affect the quality and performance of the finished products such as felting shrinkage, handle, lustre, pilling, and dyeability. These problems may be attributed mainly in the presence of wool scales on the fiber surface. Recently, chemical treatments such as oxidation and reduction are the commonly used descaling methods in the industry. However, as a result of the pollution caused by various chemical treatments, physical treatment such as low temperature plasma (LTP) treatment has been introduced recently because it is similarly capable of achieving a comparable descaling effect. Most of the discussions on the applications of LTP treatment on wool fiber were focused on applying this technique for improving the surface wettability and shrink resistance. Meanwhile, little discussion has been made on the mechanical properties, thermal properties, and the air permeability. In this paper, wool fabric was treated with LTP treatment with the use of a non-polymerizing gas, namely oxygen. After the LTP treatment, the fabrics low-stress mechanical properties, air permeability, and thermal properties were evaluated and discussed.

  2. The effects of surface treatments on rapid chloride permeability tests

    Surface treatments are commonly applied to improve the chloride resistance of concrete structures exposed to saline environments. Information on chloride ingress to surface-treated concrete is mostly provided by application of the rapid chloride permeability test (RCPT); this test is short in duration and provides rapid results. This study presents a numerical formulation, based on the extended Nernst-Plank/Poisson (NPP) equation, to model the effect of the surface treatment on a sample tested by RCPT. Predictions of the model are compared to experimental measurements. The simulations show that the results from RCPT, in terms of ionic profiles and measurement of the electric field, are dependent on the effectiveness of surface treatments. During RCPT, highly effective surface treatments cause both cations and anions to flocculate at the interface between the surface treatment and the concrete, creating a local electric field. Our numerical model includes these phenomena and presents a methodology to obtain more accurate diffusivities of the surface-treated- concrete from RCPT. © 2012 Elsevier B.V. All rights reserved.

    There have been no systematic investigations of the effects of glucocorticoid treatment on memory in a clinical population despite experimental and clinical evidence that such treatment could cause memory disturbance. We conducted both cross-sectional and longitudinal studies. In Study 1, we administered tests of both hippocampal-dependent explicit memory and hippocampal-independent implicit memory to twenty-five prednisone-treated patients with systemic disease without CNS involvement and 25 matched clinical controls. All treated patients were taking doses of 5 to 40 mg of prednisone daily for at least 1 year. The glucocorticoid-treated group performed worse than the controls on tests of explicit memory, but the groups did not differ on the implicit memory task. Multiple regression analyses suggested that elderly patients are more susceptible to memory impairment with less protracted treatment. The results of Study 2, a prospective, longitudinal study of the effects of prednisone on memory across 3 months of therapy, suggest that even acute treatment can adversely affect memory. The observed alteration in memory was not secondary to inattention, affective disturbance, generalized global cognitive decline, or severity of disease. Results reported here, combined with previous clinical and experimental reports, indicate that the risk of memory impairment should be carefully considered before initiating treatment with glucocorticoids. Conversely, use of glucocorticoids should be considered in the differential diagnosis of memory loss. Finally, the potential benefit of anti-inflammatory treatment in Alzheimer's disease might be counterbalanced by possible iatrogenic memory impairment, at least when synthetic glucocorticoids are considered.

    Neuroimaging techniques to measure the function and biochemistry of the human brain such as positron emission tomography (PET), proton magnetic resonance spectroscopy ((1)H MRS), and functional magnetic resonance imaging (fMRI), are powerful tools for assessing neurobiological mechanisms underlying the response to treatments in substance use disorders. Here, we review the neuroimaging literature on pharmacological and behavioral treatment in substance use disorder. We focus on neural effects of medications that reduce craving (e.g., naltrexone, bupropion hydrochloride, baclofen, methadone, varenicline) and that improve cognitive control (e.g., modafinil, N-acetylcysteine), of behavioral treatments for substance use disorders (e.g., cognitive bias modification training, virtual reality, motivational interventions) and neuromodulatory interventions such as neurofeedback and transcranial magnetic stimulation. A consistent finding for the effectiveness of therapeutic interventions identifies the improvement of executive control networks and the dampening of limbic activation, highlighting their values as targets for therapeutic interventions in substance use disorders.

    Full Text Available Abstract Background Whiles awaiting for the arrival of an effective and affordable malaria vaccine, there is a need to make use of the available control tools to reduce malaria risk, especially in children under five years and pregnant women. Intermittent preventive treatment (IPT has recently been accepted as an important component of the malaria control strategy. This study explored the potential of a strategy of intermittent preventive treatment for children (IPTC and timely treatment of malaria-related febrile illness in the home in reducing the parasite prevalence and malaria morbidity in young children in a coastal village in Ghana. Methods The study combined home-based delivery of IPTC among six to 60 months old and home treatment of suspected febrile malaria illness within 24 hours. All children between six and 60 months of age received intermittent preventive treatment using amodiaquine and artesunate, delivered by community assistants every four months (three times in 12 months. Malaria parasite prevalence surveys were conducted before the first and after the third dose of IPTC. Results Parasite prevalence was reduced from 25% to 3% (p Conclusion The evaluation result indicates that IPTC given three times in a year combined with timely treatment of febrile malaria illness, impacts significantly on the parasite prevalence. The marked reduction in the parasite prevalence with this strategy points to the potential for reducing malaria-related childhood morbidity and mortality, and this should be explored by control programme managers.

    Among the shape memory alloys, Fe-based have real perspectives of industrial development. However, to acquire a good shape memory effect, these alloys must undergo a thermomechanical treatment. For applcation perspective this treatment must be the simpliest as possible. In this paper, two types of treatment have been performed, based of the fact that : - the formation of the martensite ε, responsible for the shape memory effect, is sensitive to the microstructure - its reversibility is the best as possible if the austenite is previously hardened by a deformation at high temperature.

    A systematic review and network meta-analysis. To determine current treatment options of chronic low back pain (LBP) as defined by randomized controlled trials (RCTs) and to compare effectiveness of those treatments using a mixed-treatment comparison (MTC). It is important to provide an evidence-based assessment of the treatment options that exist for LBP. A systematic search of RCTs was conducted in MEDLINE and the Cochrane Collaboration Library from 1990 to 2014. From the selected studies, we extracted preoperative and postoperative ODI and VAS back pain scores, additional surgeries, and complications. Standard and network meta-analytic techniques were used. Twelve RCTs were included in the analysis: 5 total disk replacement (TDR) versus fusion; 1 TDR versus exercise and cognitive behavioral therapy (CBT); 5 fusion versus exercise and CBT; and 1 fusion versus physical therapy (PT). On the basis of MTC, with respect to ODI change scores, the pooled mean difference favoring fusion over exercise and CBT was 2.0 points (95% CI, -1.2 to 4.8). The pooled mean difference favoring TDR over exercise and CBT was 6.4 points (95% CI, 3.2-9.3). The pooled mean difference favoring fusion over PT was 8.8 points (95% CI, 4.1-13.6). The pooled mean differences favoring TDR over fusion was 4.4 points (95% CI, 2.37-6.63). For PT versus structured exercise with CBT, the pooled mean difference favoring exercise with CBT over PT was 6.8 points (95% CI, 1.5-12.8). For TDR versus PT, the pooled mean difference favoring TDR over PT was 13.2 points (95% CI, 8.0-18.4). Additional surgery rates were similar between treatment options. All 4 treatments provided some benefit to patients with chronic LBP. According to the MTC analysis, TDR may be the most effective treatment and PT the least effective treatment for chronic LBP. This review is based on a limited number of RCT studies and does not support any 1 treatment modality for all patients.

    Full Text Available Objective. This review has evaluated the effectiveness of pharmacological treatment of apathy in patients with Alzheimer’s disease (AD. Methods. A systematic literature search was conducted on published clinical trials assessing the effects of pharmacological treatment on apathy in AD over the last 10 years. Results. Fourteen studies considered of good quality were included in the analysis (4 randomized controlled trials, 9 open-label studies, and 1 retrospective analysis. Cholinesterase inhibitors were investigated in 9 studies, monoaminergic compounds such as methylphenidate and modafinil in two trials and one trial, respectively, and Ginkgo biloba (EGb 761 extract and citalopram in one study each. Cholinesterase inhibitors did not show statistical significant effect in 1 RCT study but were associated to improvement in 3 open-label studies. Methylphenidate elicited a small but significant activity accompanied by relevant side effects such as high blood pressure, cough, and osteoarticular pain. EGb 761 was well tolerated and countered apathy. Other treatments induced modest improvements or were ineffective. Conclusions. Apathy treatment remains a challenge and there is no evident advantage of any specific pharmacotherapy tested so far. The development of controlled studies according to updated guidelines for the diagnosis of apathy in patients with AD is desirable.

    In randomized trials of primary prevention, there has been interest in the persistence of a beneficial effect of therapy after treatment has been stopped. We investigated the impact of measurement error in the outcome on results of the trial of preventing hypertension (TROPHY), a trial of candesartan vs. placebo for preventing hypertension in prehypertensive subjects. We simulated the TROPHY study design, assuming that candesartan reduced blood pressure by 8/6 mm Hg during treatment, but had no carryover effect after treatment stopped. We simulated individual true blood pressures in the TROPHY-eligible range of 130-140 mm Hg for systolic blood pressure and 80-90 mm Hg for diastolic blood pressure, and added individual measurement variability. As in TROPHY, incident hypertension was defined as any three occurrences of systolic blood pressure 140 mm Hg or diastolic blood pressure 90 mm Hg. In the absence of any carryover effect, typical incidence curves for time to hypertension were similar to those from TROPHY. A significant difference in cumulative incidence 2 years after stopping treatment was detected in 80% simulated studies, giving a Type I error rate of 80%. The published data from TROPHY are consistent with a lack of carryover effect of candesartan.

    LENUS (Irish Health Repository)

    Bennett, Kathleen

    2009-01-01

    OBJECTIVE: Coronary heart disease (CHD) is associated with a large burden of disease in Ireland and is responsible for more than 6000 deaths annually. This study examined the cost-effectiveness of specific CHD treatments in Ireland. METHODS: Irish epidemiological data on patient numbers and median survival in specific groups, plus the uptake, effectiveness, and costs of specific interventions, all stratified by age and sex, were incorporated into a previously validated CHD mortality model, the IMPACT model. This model calculates the number of life-years gained (LYGs) by specific cardiology interventions to generate incremental cost-effectiveness ratios (ICERs) per LYG for each intervention. RESULTS: In 2000, medical and surgical treatments together prevented or postponed approximately 1885 CHD deaths in patients aged 25 to 84 years, and thus generated approximately 14,505 extra life-years (minimum 7270, maximum 22,475). In general, all the cardiac interventions investigated were highly cost-effective in the Irish setting. Aspirin, beta-blockers, ACE inhibitors, spironolactone, and warfarin for specific conditions were the most cost-effective interventions (< euro 3000\\/LYG), followed by the statins for secondary prevention (< euro 6500\\/LYG). Revascularization for chronic angina and primary angioplasty for myocardial infarction, although still cost-effective, had the highest ICER (between euro 12,000 and euro 20,000\\/LYG). CONCLUSIONS: Using a comprehensive standardized methodology, cost-effectiveness ratios in this study clearly favored simple medical treatments for myocardial infarction, secondary prevention, angina, and heart failure.

    Full Text Available Additional intervention and medical treatment of complications may follow the primary treatment of a ureteral stone. We investigated the cost of the treatment of ureteral stone(s within 45 days after initial intervention by means of retrospective analysis of the National Health Insurance Research Database of Taiwan. All patients of ages ≥20 years diagnosed with ureteral stone(s( International Classification of Diseases, Ninth Revision, Clinical Modification/ICD-9-CM: 592.1 from January 2001 to December 2011 were enrolled. We included a comorbidity code only if the diagnosis appeared in at least 2 separate claims in a patient’s record. Treatment modalities (code included extracorporeal shock-wave lithotripsy (SWL; 98.51, ureteroscopic lithotripsy (URSL; 56.31, percutaneous nephrolithotripsy (PNL; 55.04, (open ureterolithotomy (56.20, and laparoscopy (ie, laparoscopic ureterolithotomy; 54.21. There were 28 513 patients with ureteral stones (13 848 men and 14 665 women in the randomized sample of 1 million patients. The mean cost was 526.4 ± 724.1 United States Dollar (USD. The costs of treatment were significantly increased in patients with comorbidities. The costs of treatment among each primary treatment modalities were 1212.2 ± 627.3, 1146.7 ± 816.8, 2507.4 ± 1333.5, 1533.3 ± 1137.1, 2566.4 ± 2594.3, and 209.8 ± 473.2 USD in the SWL, URSL, PNL, (open ureterolithotomy, laparoscopy (laparoscopic ureterolithotomy, and conservative treatment group, respectively. In conclusion, URSL was more cost-effective than SWL and PNL as a primary treatment modality for ureteral stone(s when the possible additional costs within 45 days after the initial operation were included in the calculation.

    Full Text Available Heart Transplantation (HTx to date remains the most effective and radical method of treatment of patients with end-stage heart failure. The defi cit of donor hearts is forcing to resort increasingly to the use of different longterm mechanical circulatory support systems, including as a «bridge» to the follow-up HTx. According to the ISHLT Registry the number of recipients underwent cardiopulmonary bypass surgery increased from 40% in the period from 2004 to 2008 to 49.6% for the period from 2009 to 2015. HTx performed in repeated patients, on the one hand, involves considerable technical diffi culties and high risks; on the other hand, there is often no alternative medical intervention to HTx, and if not dictated by absolute contradictions the denial of the surgery is equivalent to 100% mortality. This review summarizes the results of a number of published studies aimed at understanding the immediate and late results of HTx in patients, previously underwent open heart surgery. The effect of resternotomy during HTx and that of the specifi c features associated with its implementation in recipients previously operated on open heart, and its effects on the immediate and long-term survival were considered in this review. Results of studies analyzing the risk factors for perioperative complications in repeated recipients were also demonstrated. Separately, HTx risks after implantation of prolonged mechanical circulatory support systems were examined. The literature does not allow to clearly defi ning the impact factor of earlier performed open heart surgery on the course of perioperative period and on the prognosis of survival in recipients who underwent HTx. On the other hand, subject to the regular fl ow of HTx and the perioperative period the risks in this clinical situation are justifi ed as a long-term prognosis of recipients previously conducted open heart surgery and are comparable to those of patients who underwent primary HTx.

    Full Text Available We analyzed the effectiveness of two psychological therapies to treat depression in the Culiacan population, Mexico. According to criteria of MINI (international Neuropsychiatric interview, 30 individuals from a total of 300 were selected and diagnosed with some kind of depression. Patients were divided in three groups: 1 treatment with hypnosis therapy, 2 treatment with Gestalt-hypnosis therapy, and 3 control group. Before and after the treatments the Beck Anxiety Inventory (BAI was applied to know the depression level of the analyzed groups. The results show that the three groups were presenting a moderated level of depression. The groups under hypnosis therapy and Gestalt-hypnosis therapy show statistical differences between pre-test and post-test. The hypnosis therapy shows significant statistic differences to treat depression with respect to the other two groups. In conclusion, the therapeutic hypnosis is an effective treatment and has relevance to treat depression, while other therapeutic treatments tend to be slow and with minor result. This study is the first of this kind carried out in Culiacan in Sinaloa, Mexico.

    Full Text Available Purpose: To compare the effects of different methods of surface treatment on enamel roughness. Materials and Methods: Ninety human maxillary first premolars were randomly divided into three groups (n=30 according to type of enamel surface treatment: I, acid etching; II, Er:YAG laser; III, Nd:YAG laser. The surface roughness of enamel was measured with a noncontact optical profilometer. For each enamel sample, two readings were taken across the sample—before enamel surface treatment (T1 and after enamel surface treatment (T2. The roughness parameter analyzed was the average roughness (Ra. Statistical analysis was performed using a Paired sample t test and the post-hoc Mann- Whitney U test, with the significance level set at 0.05. Results: The highest Ra (average roughness values were observed for Group II, with a significant difference with Groups I and III (P<0.001. Ra values for the acid etching group (Group I were significantly lower than other groups (P<0.001. Conclusion: Surface treatment of enamel with Er:YAG laser and Nd:YAG laser results in significantly higher Ra than acid-etching. Both Er:YAG laser or Nd:YAG laser can be recommended as viable treatment alternatives to acid etching.

    Treatment with omalizumab has shown a positive effect on food allergies, but no dosages are established. Basophil allergen threshold sensitivity (CD-sens) can be used to objectively measure omalizumab treatment efficacy and correlates with the outcome of double-blind placebo-controlled food challenge to peanut. To evaluate whether individualized omalizumab treatment monitored by CD-sens could be an effective intervention for suppression of allergic reactions to peanut. Severely peanut allergic adolescents (n = 23) were treated with omalizumab for 8 weeks, and CD-sens was analysed before and after. Based on whether CD-sens was suppressed after 8 weeks, the patients either were subject to a peanut challenge or received eight more weeks with increased dose of omalizumab, followed by peanut challenge or another 8-week cycle of omalizumab. IgE and IgE-antibodies to peanut and its components were analysed before treatment. After individualized omalizumab treatment (8-24 weeks), all patients continued with an open peanut challenge with no (n = 18) or mild (n = 5) objective allergic symptoms. Patients (n = 15) needing an elevated omalizumab dose (ED) to suppress CD-sens had significantly higher CD-sens values at baseline 1.49 (0.44-20.5) compared to those (n = 8) who managed with normal dose (ND) 0.32 (0.24-5.5) (P omalizumab, monitored by CD-sens, is an effective and safe treatment for severe peanut allergy. The ratio of IgE-ab to storage protein Ara h 2/IgE as well as CD-sens to peanut may predict the need of a higher omalizumab dose.

    Machado-Joseph disease (MJD) is an inherited neurodegenerative disease, caused by a CAG repeat expansion within the coding region of ATXN3 gene, and which currently lacks effective treatment. In this work we tested the therapeutic efficacy of chronic treatment with valproic acid (VPA) (200mg/kg), a compound with known neuroprotection activity, and previously shown to be effective in cell, fly and nematode models of MJD. We show that chronic VPA treatment in the CMVMJD135 mouse model had limited effects in the motor deficits of these mice, seen mostly at late stages in the motor swimming, beam walk, rotarod and spontaneous locomotor activity tests, and did not modify the ATXN3 inclusion load and astrogliosis in affected brain regions. However, VPA chronic treatment was able to increase GRP78 protein levels at 30 weeks of age, one of its known neuroprotective effects, confirming target engagement. In spite of limited results, the use of another dosage of VPA or of VPA in a combined therapy with molecules targeting other pathways, cannot be excluded as potential strategies for MJD therapeutics.

    Low- and middle-income countries lack information on contextualised mental health interventions to aid resource allocation decisions regarding healthcare. To undertake a cost-effectiveness analysis of treatments for depression contextualised to Chile. Using data from studies in Chile, we developed a computer-based Markov cohort model of depression among Chilean women to evaluate the cost-effectiveness of usual care or improved stepped care. The incremental cost-effectiveness ratio (ICER) of usual care was I$113 per quality-adjusted life-year (QALY) gained, versus no treatment, whereas stepped care had an ICER of I$468 per QALY versus usual care. This compared favourably with Chile's per-capita GDP. Results were most sensitive to variation in recurrent episode coverage, marginally sensitive to cost of treatment, and insensitive to changes in health-state utility of depression and rate of recurrence. Our results suggest that treatments for depression in low- and middle-income countries may be more cost-effective than previously estimated.

    The transpalatal arch (TPA) can be used as an adjunct during orthodontic treatment to help control the movement of the maxillary first molars in 3 dimensions, including producing molar rotation and uprighting, maintaining transverse dimensions posteriorly during treatment, and maintaining leeway spaces during the transition of the dentition. The purpose of this retrospective cephalometric study was to test an additional function of the TPA: its ability to enhance orthodontic anchorage during extraction treatment. Records consisting of pretreatment and posttreatment cephalograms were gathered from several orthodontic practices that used an .018 x .025-in preangulated appliance. All patients were white and had 4 first premolars extracted as part of their treatment protocol. Patients were treated either with or without a TPA of the soldered Goshgarian design. Patients were excluded if headgear or any other auxiliary anchorage device beside the TPA was used during treatment. Matched samples of 30 patients were identified based on sex, age at the start of treatment, treatment duration, and cervical vertebral maturation stage. Statistical comparisons were made with nonparametric statistical tests. Analysis of the changes from pretreatment to posttreatment for the TPA and the no-TPA groups showed no statistically significant differences in any of the variables examined. The net difference for both vertical and mesial movement of the maxillary first molar in relation to the maxilla between the 2 groups was 0.4 mm, with the no-TPA group in a more downward and forward position. Although the usefulness of the TPA for the abovementioned functions is not negated, it does not provide a significant effect on either the anteroposterior or the vertical position of the maxillary first molars during extraction treatment.

    Full Text Available Purpose: A recent study suggests that transcranial brain targeted light treatment via ear canals may have physiological effects on brain function studied by functional magnetic resonance imaging (fMRI techniques in humans. We tested the hypothesis that bright light treatment could improve psychomotor speed in professional ice hockey players. Methods: Psychomotor speed tests with audio and visual warning signals were administered to a Finnish National Ice Hockey League team before and after 24 days of transcranial bright light or sham treatment. The treatments were given during seasonal darkness in the Oulu region (latitude 65 degrees north when the strain on the players was also very high (10 matches during 24 days. A daily 12-min dose of bright light or sham (n = 11 for both treatment was given every morning between 8–12 am at home with a transcranial bright light device. Mean reaction time and motor time were analyzed separately for both psychomotor tests. Analysis of variance for repeated measures adjusted for age was performed. Results: Time x group interaction for motor time with a visual warning signal was p = 0.024 after adjustment for age. In Bonferroni post-hoc analysis, motor time with a visual warning signal decreased in the bright light treatment group from 127 ± 43 to 94 ± 26 ms (p = 0.024 but did not change significantly in the sham group 121 ± 23 vs. 110 ± 32 ms (p = 0.308. Reaction time with a visual signal did not change in either group. Reaction or motor time with an audio warning signal did not change in either the treatment or sham group. Conclusion: Psychomotor speed, particularly motor time with a visual warning signal, improves after transcranial bright light treatment in professional ice-hockey players during the competition season in the dark time of the year.

  1. Proteins in Soy Might Have a Higher Role in Cancer Prevention than Previously Expected: Soybean Protein Fractions Are More Effective MMP-9 Inhibitors Than Non-Protein Fractions, Even in Cooked Seeds

    Full Text Available The search for anticancer MMP-9 inhibitors (MMPIs in food products has become a major goal for research. MMPIs in soy have been related only to saponins and isoflavones, but recently, low specific protein fractions in soybeans were shown to reduce MMP-9 activity as well. The present work aimed at comparing the MMPI potential of protein fractions (P and non-protein fractions (NP isolated from soybean seeds, before and after soaking and cooking, mimicking dietary exposures. Reverse and substrate zymography, as well as a fluoregenic DQ gelatin assay were used to evaluate MMP-9 activities. Colon cancer cell migration and proliferation was also tested in HT29 cells. Regarding MMP-9 inhibition, proteins in soy presented IC50 values 100 times lower than non-protein extracts, and remained active after cooking, suggesting that proteins may be more effective MMP-9 inhibitors than non-protein compounds. Using the determined IC50 concentrations, NP fractions were able to induce higher inhibitions of HT29 cell migration and proliferation, but not through MMP-9 inhibition, whilst protein fractions were shown to specifically inhibit MMP-9 activity. Overall, our results show that protein fractions in soybeans might have a higher role in soy-related cancer prevention as MMPIs than previously expected. Being nontoxic and active at lower concentrations, the discovery of these heat-resistant specific MMPI proteins in soy can be of significant importance for cancer preventive diets, particularly considering the increasing use of soy proteins in food products and the controversy around isoflavones amongst consumers.

    Cortical bone, the dominant component of the human skeleton by volume, plays a key role in protecting bones from fracture. We analyzed the cortical bone effects of teriparatide treatment in postmenopausal women with osteoporosis who had previously received long-term alendronate (ALN) therapy or were treatment naïve (TN). Tetracycline-labeled paired iliac crest biopsies obtained from 29 ALN-pretreated and 16 TN women were evaluated for dynamic histomorphometric parameters of bone formation at the periosteal, endocortical and intracortical bone compartments, before and after 24months of teriparatide treatment. At baseline, the frequency of specimens without any endocortical and periosteal tetracycline labeling, and the percentage of quiescent osteons, was higher in the ALN than the TN group. Endocortical and periosteal mineralizing surface (MS/BS%), periosteal bone formation rate (BFR/BS), mineral apposition rate (MAR) and the number of intracortical forming osteons were significantly lower in the ALN-pretreated patients than in the TN group. Following teriparatide treatment, the frequency of endocortical and periosteal unlabeled biopsies decreased; in the ALN-pretreated group the percentage of quiescent osteons decreased and, in contrast, forming and resorbing osteons were increased. Teriparatide treatment resulted in significant increases of MAR in the endocortical, and MS/BS% in the periosteal compartment in the ALN-pretreated group. Most indices of bone formation remained lower in the ALN-pretreated group compared with the TN group at study end. Endocortical wall width was increased in both ALN-pretreated and TN groups. Cortical porosity and cortical thickness were significantly increased in the ALN-pretreated group after teriparatide treatment. Our results suggest that 24months of teriparatide treatment increases cortical bone formation and cortical turnover in patients who were either TN or had previous ALN therapy.

    Viallet, Benoit; Daran, Emmanuelle; Malaquin, Laurent

    2003-01-01

    Benzocyclobutene (BCB) is a dielectric polymer resin used in microelectronics for its physical properties and its chemical resistance. UV/ozone photochemical treatment modifies the chemical properties of BCB: It creates a near SiO 2 composition oxidized surface layer and degrades the polymer structure of BCB. The oxidized surface layer can be etched with fluoride acid and the degraded layer underneath is soluble with acetone. These BCB chemical modifications may be useful for BCB reworking after polymerization. UV/ozone treatment also has an effect on surface characteristics improving the surface tension and decreasing surface roughness of BCB

  6. Parameter trajectory analysis to identify treatment effects of pharmacological interventions.

    Directory of Open Access Journals (Sweden)

    Christian A Tiemann

    Full Text Available The field of medical systems biology aims to advance understanding of molecular mechanisms that drive disease progression and to translate this knowledge into therapies to effectively treat diseases. A challenging task is the investigation of long-term effects of a (pharmacological treatment, to establish its applicability and to identify potential side effects. We present a new modeling approach, called Analysis of Dynamic Adaptations in Parameter Trajectories (ADAPT, to analyze the long-term effects of a pharmacological intervention. A concept of time-dependent evolution of model parameters is introduced to study the dynamics of molecular adaptations. The progression of these adaptations is predicted by identifying necessary dynamic changes in the model parameters to describe the transition between experimental data obtained during different stages of the treatment. The trajectories provide insight in the affected underlying biological systems and identify the molecular events that should be studied in more detail to unravel the mechanistic basis of treatment outcome. Modulating effects caused by interactions with the proteome and transcriptome levels, which are often less well understood, can be captured by the time-dependent descriptions of the parameters. ADAPT was employed to identify metabolic adaptations induced upon pharmacological activation of the liver X receptor (LXR, a potential drug target to treat or prevent atherosclerosis. The trajectories were investigated to study the cascade of adaptations. This provided a counter-intuitive insight concerning the function of scavenger receptor class B1 (SR-B1, a receptor that facilitates the hepatic uptake of cholesterol. Although activation of LXR promotes cholesterol efflux and -excretion, our computational analysis showed that the hepatic capacity to clear cholesterol was reduced upon prolonged treatment. This prediction was confirmed experimentally by immunoblotting measurements of SR-B1

    1995-03-01

    Measures of attention and implicit memory for threatening words were obtained from anxious patients before and after psychological treatment, and compared with data from non-anxious control Ss collected over the same period. Findings confirmed the expectation that the presence of threatening distractors would be associated with greater interference with the performance of anxious patients than with that of controls, in both color-naming and attentional search tasks, but failed to confirm the previous finding of related differences in priming on a word completion task. Treatment significantly reduced selective interference effects in anxious patients, and abolished evidence of differences between the treated patients and controls. It is suggested that cognitive bias effects in anxiety may either depend on state factors alone, or may represent a more enduring individual difference that becomes apparent only when vulnerable individuals are primed by mood state or stressful events.

    Isoniazid treatment of latent tuberculosis infection (LTBI) is commonly prescribed in refugees and immigrants. We aimed to assess understanding of information provided about LTBI, its treatment and potential side effects. A questionnaire was administered in clinics at a tertiary hospital. Total Knowledge (TKS) and Total Side Effect Scores (TSES) were derived. Logistic regression analyses were employed to correlate socio-demographic factors with knowledge. Fifty-two participants were recruited, 20 at isoniazid commencement and 32 already on isoniazid. The average TKS were 5.04/9 and 6.23/9 respectively and were significantly associated with interpreter use. Approximately half did not know how tuberculosis was transmitted. The average TSES were 5.0/7 and 3.5/7 respectively, but were not influenced by socio-demographic factors. There was suboptimal knowledge about LTBI. Improvements in health messages delivered via interpreters and additional methods of distributing information need to be developed for this patient population.

    To determine the frequency of tests done in the year before elective surgery that might substitute for preoperative screening tests and to determine the frequency of test results that change from a normal value to a value likely to alter perioperative management. Retrospective cohort analysis of computerized laboratory data (complete blood count, sodium, potassium, and creatinine levels, prothrombin time, and partial thromboplastin time). Urban tertiary care Veterans Affairs Hospital. Consecutive sample of 1109 patients who had elective surgery in 1988. At admission, 7549 preoperative tests were done, 47% of which duplicated tests performed in the previous year. Of 3096 previous results that were normal as defined by hospital reference range and done closest to the time of but before admission (median interval, 2 months), 13 (0.4%; 95% CI, 0.2% to 0.7%), repeat values were outside a range considered acceptable for surgery. Most of the abnormalities were predictable from the patient's history, and most were not noted in the medical record. Of 461 previous tests that were abnormal, 78 (17%; CI, 13% to 20%) repeat values at admission were outside a range considered acceptable for surgery (P less than 0.001, frequency of clinically important abnormalities of patients with normal previous results with those with abnormal previous results). Physicians evaluating patients preoperatively could safely substitute the previous test results analyzed in this study for preoperative screening tests if the previous tests are normal and no obvious indication for retesting is present.

    An atmospheric plasma system using Helium gas was developed. The effect of helium plasma treatment on skin scaffold surface was studied by scanning electron microscopy (SEM). The changes of skin scaffold surfaces before and after helium plasma treatment was recorded. The surface of skin scaffold changed with the prolonged of helium plasma treatment time. The depth of helium plasma penetration was studied using methylene blue dye staining method. The methylene blue will detect the presence or absence of an oxygen that was induced from plasma excitation. The presence of the oxygen indicated on the depth of helium plasma penetration. Results showed plasma are able to penetrate 4mm of skin scaffold after 1200 seconds of exposure.

  11. The effect of heat treatment on phosphorus segregation in a submerged-arc weld metal

    1999-01-01

    Intergranular fracture (IGF) has been observed in carbon-manganese steels after irradiation or high temperature exposure for prolonged periods. The effect is associated with an increase in the ductile-brittle transition temperature and has been related to phosphorus diffusion to grain boundaries. Phosphorus also diffuses thermally at the temperatures used for post-weld heat treatments such that in principle, the slightly different heat treatments given to different parts of a large vessel could lead to differing grain boundary phosphorus coverage and hence susceptibility to IGF. The effect of typical heat treatments on phosphorus coverage has been investigated using a finite difference model based on a theory that has been fitted to a wide range of constant temperature data. Regardless of previous history, the grain boundary coverage of phosphorus was predicted to depend on the final anneal and cooling rate. These differed insufficiently in the typical heat treatments to produce significant differences in segregation. It was concluded that the ductile-brittle transition temperature in submerged-arc welds would be unaffected in vessels that had seen typical post-weld heat treatments

    Full Text Available Objective: The aim of this retrospective study is to evaluate the treatment outcomes in patients with toxic nodular goiter (TNG that received radioiodine treatment (RAIT and to determine the influence of age, gender, nodule size, I-131 dose, underlying etiology and antithyroid drugs on the outcomes of RAIT. Methods: Two hundred thirty three patients (mean 64±10 years old with TNG that received RAIT were included in the study. Treatment success was analyzed according to demographic (age and gender and clinical data (thyroid function tests before and after RAIT, thyroid sonography and scintigraphy, I-131 dose, antithyroid drugs. A fixed dose of 555 MBq was administered to patients with nodules smaller than 2 cm in diameter and of 740 MBq to patients with nodules larger than 2 cm. Hyperthyroidism treatment success was defined as achieving hypothyroidism or euthyroidism six months after RAIT. Results: In our study, the cure rate was 93.9% six months after RAIT. Hypothyroidism was observed in 74 (31.7% patients, and euthyroidism was achieved in 145 (62.2% patients while 14 (6% patients remained in hyperthyroid state. Age and gender did not affect treatment outcomes. No correlation was found between underlying etiology or antithyroid drugs and therapeutic effectiveness. The effectiveness of RAIT was better in patients with nodules smaller than 2 cm. Conclusion: We observed that high cure rates were obtained in patients with TNG with 555 MBq and 740 MBq doses of I-131. While nodule diameter and RAI dose are important factors for treatment efficacy; age, gender, underlying etiology and antithyroid drugs do not affect the outcome of RAIT.

    Full Text Available Background. The success of endodontic treatment is provided by a thorough instrumental and antiseptic treatment of infected root canals, and it depends on the composition of filling material, the degree of adhesion to dentin, hermetic obturation of apical foramen, solubility of sealer. Objective. The study was aimed to evaluate the effectiveness of root canal obturation with BioRootTM RCS sealer in the treatment of patients with chronic apical periodontitis. Methods. Endodontic treatment of 23 teeth in 20 patients with chronic apical periodontitis by method of lateral compaction of gutta-percha was carried out. In the main group root canals were obturated with BioRootTM RCS, in the control group the canals were filled with Apexit Plus. The percentage of efficient or non-efficient cases was evaluated on the basis of radiographic comparison of treated chronic apical periodontitis immediately after obturation, in three, six months and one year. Radiographic conditions were defined as existing state, improvement and worsening. Results. In a year of dynamic evaluation the final results were: in the main group – 54.55% of the patients had complete bone healing, in 27.27% of cases the focus of bone destruction was decreased by ½ or more of the initial sizes, 18.18% – resorption lesion was decreased by less than ½; in the control group – 33.33% of improvement, 25.0% of existing state and 41.66% of worsening. Conclusions. BioRootTM RCS using for root canals obturation in the treatment of chronic apical periodontitis we proved the high effectiveness of the treatment undertaken: complete healing or improvement of radiographic conditions of periapical bone destruction with X-ray signs of bone regeneration.

    The aim of this study was to characterize the treatment response and serious adverse events of ledipasvir plus sofosbuvir therapies in Japanese patients infected with hepatitis C virus (HCV) genotype 1 (GT1). This retrospective study analyzed 240 Japanese HCV GT1 patients treated for 12 weeks with 90 mg of ledipasvir plus 400 mg of sofosbuvir daily. Sustained virological response at 12 weeks post-treatment (SVR12) was achieved in 236 of 240 (98.3%) patients. Among treatment-naïve patients, SVR12 was achieved in 136 of 138 (98.6%) patients, and among treatment-experienced patients, SVR12 was achieved in 100 of 102 (98.0%) patients. In patients previously treated with peginterferon plus ribavirin with various HCV NS3/4A inhibitors, 100% SVR rates (25/25) were achieved. Two relapsers had HCV NS5A resistance-associated variants (RAVs), but no HCV NS5B-S282 was observed after they relapsed. We experienced two patients with cardiac events during treatment. In conclusion, combination of ledipasvir plus sofosbuvir for 12 weeks is a potential therapy for HCV GT1 patients. Caution is needed for HCV NS5A RAVs, which were selected by HCV NS5A inhibitors and cardiac adverse events.

    The most common surgical approach in case of local tumor recurrence after quadrantectomy and radiotherapy is salvage mastectomy. Breast reconstruction is the subsequent phase of the treatment and the plastic surgeon has to operate on previously irradiated and manipulated tissues. The medical literature highlights that breast reconstruction with tissue expanders is not a pursuable option, considering previous radiotherapy a contraindication. The purpose of this retrospective study is to evaluate the influence of previous radiotherapy on 2-stage breast reconstruction (tissue expander/implant). Only patients with analogous timing of radiation therapy and the same demolitive and reconstructive procedures were recruited. The results of this study prove that, after salvage mastectomy in previously irradiated patients, implant reconstruction is still possible. Further comparative studies are, of course, advisable to draw any conclusion on the possibility to perform implant reconstruction in previously irradiated patients.

    Traditionally, pelvic floor retraining for faecal incontinence or obstructed defaecation has been delivered to patients through individual sessions with a specialist pelvic floor nurse, a resource-intensive practice. This study aimed to assess whether a similar outcome can be achieved by delivering retraining to patients in small groups, allowing considerable savings in the use of resources. Data were collected prospectively in a pelvic floor database. Patients received pelvic floor retraining either individually or in a small group setting and completed baseline and follow-up questionnaires. Two hundred and fifteen patients were treated, 119 individually and 96 in a small group setting. Scores before and after treatment for the two settings were compared for the Gastrointestinal Quality of Life Index, the Fecal Incontinence Severity Index and the Patient Assessment of Constipation Symptoms. Additionally patients receiving group treatment completed a short questionnaire on their experience. The median change in Gastrointestinal Quality of Life Index score was 5 (range -62 to 73) for individual treatment and 4 (range -41 to 47) for group treatment, both showing statistically significant improvement. However, there was no significant difference between the settings. Similar results were obtained with the Fecal Incontinence Severity Index and Patient Assessment of Constipation Symptoms scores for the faecal incontinence and obstructed defaecation subgroups respectively. The majority of patients experienced symptomatic improvement following pelvic floor retraining and there was no significant difference in the resulting improvement according to treatment setting. As treatment costs are considerably less in a group setting, group pelvic floor retraining is more cost-effective than individual treatment.

    Whey proteins, enriched protein fractions from milk, are of great interest as ingredients due to nutritional value associated with its functional properties. These proteins could have their structural properties improved when some treatments are applied, such as thermal and gamma irradiation or when some compounds are added. The current work aimed to study the viscometer behavior of whey dispersions submitted to two different combined treatments: (1) thermal plus irradiation and (2) thermal plus vacuum and N 2 plus irradiation. Dispersions of whey protein in water (5% and 8% protein (w/v) base) and containing proteins and glycerol at ratios 1:1 and 2:1 (protein:glycerol) were submitted to both combined treatments. The irradiation doses were 0, 5, 15 and 25 kGy. The viscosity of the two combined treatments and for four levels of absorbed doses is presented and the combined effects are discussed. The thermal treatment combined with gamma irradiation contributed to increase the viscosity as irradiation doses increases for both (5% and 8%) concentrations of proteins (p<0.05). For protein and glycerol solutions, the irradiation dose seemed to result in a slightly increase. The vacuum applied before the irradiation showed a small contribution

    Genetic variants within some cytokine receptor genes have been associated with MS susceptibility, including IL7RA and IL2RA. As these genes are expressed by cells targeted by immune-modulatory drugs, we explored the potential role of their gene products as biomarkers in monitoring MS treatment. We assessed the impact of natalizumab followed by fingolimod on the intra-individual changes of plasma protein levels of sIL-7Rα, sIL-2Rα and also sIL-6R and sgp130 in MS patients. During natalizumab treatment we observed a decline in sgp130 and sIL-7Rα levels, while subsequent fingolimod treatment lead to increased sgp130 and sIL-7Rα and decreased sIL-2Rα levels. In addition, during fingolimod treatment sIL-7Rα levels were increasing significantly more in patients homozygous for the MS risk genotype of rs6897932. We also observed an effect of the MS associated rs71624119 on sgp130 levels. These results may elucidate the pharmacodynamics of treatments and help identify biomarkers for MS outcomes.

    This study was designed to probe the psychological factors adolescent orthodontic patients, the role of body image and self-esteem in the whole process of orthodontic treatment and the impact on the efficacy and satisfaction of orthodontic. Five hundred and twenty-eight patients were selected in this study. The Aesthetic Component of the Index of Orthodontic Treatment Need (IOTN-AC) , Rosenberg Self-Esteem Scale (SES), Negative Physical Self-General (NPS-G) and other body analysis scale study after orthodontic lasted 18-24 months were used to investigate the role of body image in adolescent orthodontic treatment. Esthetic evaluation of patients teeth after correction had been significantly improved, patient self-evaluation difference IOTN-AC doctor evaluation, Psychosocial Impact of Dental Aesthetics Questionnaire-tooth confidence, aesthetic concerns, psychological impact and social function were significantly improved. The improvement of the dental aesthetics component (T2 when doctors evaluate IOTN-AC) was positively correlated with the evaluation of the efficacy, and was significantly negatively correlated with the negative emotions of patients at baseline. Negative body image-dental dissatisfied-cognitive component and the affective component, the overall negative body image and negative emotions can predict patient satisfaction with treatment efficacy. Orthodontic treatment not only improves the self-aesthetic evaluation of adolescent patients, but also has a positive effect on the mental health of adolescent patients.

    Abstract Objectives: Osteoporosis remains a clinical challenge. Teriparatide is an anabolic drug and alendronate is an antiresorptive agent; both are used in the treatment of osteoporosis. Comprehensive reviews investigating the comparative safety and efficacy of teriparatide versus alendronate are scarce. Therefore, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the safety and efficacy of teriparatide versus alendronate for the treatment of postmenopausal osteoporosis. Methods: We conducted a comprehensive literature review of the PubMed, EMBASE, Cochrane Controlled Trials Registry, and the China Academic Journal Network Publishing databases for relevant RCTs of teriparatide versus alendronate in postmenopausal osteoporosis patients. Outcome measures were percentage change in lumbar spine and femoral neck bone mineral density (BMD) and incidence of vertebral and nonvertebral fractures. Effect size was reported as weighted mean differences (WMDs) for continuous outcomes and odds ratios (OR) for dichotomous outcomes, with associated 95% confidence intervals (CIs). Results: Six trials involving 618 patients were included. The meta-analysis demonstrated a significant increase in lumbar spine BMD (WMD: 3.46, 95% CI: 2.15–4.77, P osteoporosis patients treated with teriparatide compared with alendronate for 6 to 18 months. These beneficial effects were apparent in the lumbar spine at 12 months of treatment (WMD: 4.49, 95% CI: 2.57–6.40, P osteoporosis. The efficacy and safety of long-term teriparatide and alendronate treatment in postmenopausal osteoporosis should be further investigated in clinical trials. PMID:28538396

    Lactoferrin (LF) is a multifunctional protein that exerts important activities in the neonate through its presence in milk, and also in other external mucosas, acting as a defense protein of innate immunity. The addition of bovine LF to infant formula and also to other functional products and cosmetics has increased during the last decades. Consequently, it is essential to know the effect that the technological processes, necessary to elaborate those products, have on LF activity. In this study, we have revised the effect of classical treatments on lactoferrin structure and activity, such as heat treatment or drying, and also of emerging technologies, like high pressure or pulsed electric field. The results of the studies included in this review indicate that LF stability is dependent on its level of iron-saturation and on the characteristics of the treatment media. Furthermore, the studies revised here reveal that the non-thermal treatments are interesting alternatives to the traditional ones, as they protect better the structure and activity of lactoferrin. It is also clear the need for research on LF encapsulation by different ways, to protect its properties before it reaches the intestine. All this knowledge would allow designing processes less harmful for LF, thus maintaining all its functionality. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Conclusions: Thinner EMT before estrogen treatment requires longer treatment duration and predicts poorer treatment outcomes. The effectiveness of treatment depends on the duration of estrogen administration. Assisted reproductive outcomes of patients whose treatment is successful (i.e., achieves an EMT ≥8 mm are similar to those of controls. The quality of embryos transferred is an important predictor of assisted reproductive outcomes in patients treated successfully with exogenous estrogen.

  4. The effect of small intestine heterogeneity on irreversible electroporation treatment planning.

    2014-09-01

    Nonthermal irreversible electroporation (NTIRE) is an ablation modality that utilizes microsecond electric fields to produce nanoscale defects in the cell membrane. This results in selective cell death while preserving all other molecules, including the extracellular matrix. Here, finite element analysis and experimental results are utilized to examine the effect of NTIRE on the small intestine due to concern over collateral damage to this organ during NTIRE treatment of abdominal cancers. During previous studies, the electrical treatment parameters were chosen based on a simplified homogeneous tissue model. The small intestine, however, has very distinct layers, and a more realistic model is needed to further develop this technology for precise clinical applications. This study uses a two-dimensional finite element solution of the Laplace and heat conduction equations to investigate how small intestine heterogeneities affect the electric field and temperature distribution. Experimental results obtained by applying NTIRE to the rat small intestine in vivo support the heterogeneous effect of NTIRE on the tissue. The numerical modeling indicates that the electroporation parameters chosen for this study avoid thermal damage to the tissue. This is supported by histology obtained from the in vivo study, which showed preservation of extracellular structures. The finite element model also indicates that the heterogeneous structure of the small intestine has a significant effect on the electric field and volume of cell ablation during electroporation and could have a large impact on the extent of treatment. The heterogeneous nature of the tissue should be accounted for in clinical treatment planning.

    Currently, no treatments exist for patellar tendinopathy (PT) that guarantee quick and full recovery. Our objective was to assess which treatment option provides the best chance of clinical improvement and to assess the influence of patient and injury characteristics on the clinical effect of these treatments. A secondary analysis was performed on the combined databases of 3 previously performed double-blind randomized controlled trials. In total, 138 patients with PT were included in the analysis. Participants were divided into 5 groups, based on the treatment they received: Extracorporeal shockwave therapy (ESWT) (n = 31), ESWT plus eccentric training (n = 43), eccentric training (n = 17), topical glyceryl trinitrate patch plus eccentric training (n = 16), and placebo treatment (n = 31). Clinical improvement (increase of ≥13 points on the Victorian Institute of Sport Assessment-Patella score) after 3 months of treatment. Fifty-two patients (37.7%) improved clinically after 3 months of treatment. Odds ratios (ORs) for clinical improvement were significantly higher in the eccentric training group (OR 6.68, P = 0.009) and the ESWT plus eccentric training group (OR 5.42, P = 0.015) compared with the other groups. We found evidence that a high training volume, a longer duration of symptoms, and older age negatively influence a treatment's clinical outcome (trend toward significance). Our study confirmed the importance of exercise, and eccentric training in particular, in the management of PT. The role of ESWT remains uncertain. Further research focusing on the identified prognostic factors is needed to be able to design patient-specific treatment protocols for the management of PT.

    Weightbath hydrotraction treatment (WHT) is a simple noninvasive effective method of hydro- or balneotherapy to stretch the spine or lower limbs, applied successfully in hospitals and health resort sanitaria in Hungary for more than fifty years. This study aims to introduce WHT with its biomechanical and clinical effects. History, development, equipment, modes of application, biomechanics, spinal traction forces and elongations, indications and contraindications of WHT are precented. The calculation of traction forces acting along the spinal column during the treatment is described together with the mode of suspension and the position of extra weight loads applied. The biomechanics of the treatment are completed by in vivo measured elongations of lumbar segments using a special underwater ultrasound measuring method. The clinical effects, indications, and contraindications of the treatment are also presented. In the underwater cervical suspension of a human body, approximately 25 N stretching load occurs in the cervical spine, and about 11 N occurs in the lumbar spine. By applying extra weights, the above tensile forces along the spinal column can be increased. Thus, the traction effect can be controlled by applying such loads during the treatment. Elongations of segments L3-L4, L4-L5, and L5-S1 were measured during the usual WHT of patients suspended cervically in water for 20 minutes, loaded by 20-20 N lead weights on the ankles. The mean initial elastic elongations of spinal segments were about 0.8 mm for patients aged under 40 years, 0.5 mm between 40-60 years, and 0.2 mm for patients over 60 years. The mean final viscoelastic elongations were 1.5 mm, 1.2 mm, and 0.6 mm for the same age classes, respectively. No significant difference was found between the sexes regarding age-dependence in tension. WHT for discopathy showed significant improvement of clinical parameters, which was still evident three months later, as demonstrated by using a controlled pilot

    We sought to evaluate the effects of oral testosterone undecanoate treatment based on the temporary growth of penis and the complications of surgery in children with microphallic hypospadias. A total of 72 randomized consecutive children with microphallic hypospadias were included in the study from March 2011 to September 2013. While 34 children were treated with oral testosterone undecanoate treatment prior to surgery on time (group 1), 36 children did not receive any treatment preoperatively (group 2). All children underwent hypospadias repair using transverse preputial island flap (Duckett technique) urethroplasty or combination of Duckett and Thiersch-Duplay techniques. Penile length, diameter, serum testosterone level, and secondary effects were recorded before and after therapy in group 1. Postoperative complications were assessed with respect to fistulas, urethral strictures, diverticula, meatal stenosis, and glanular dehiscence in both groups. Mean penile length and diameter increased significantly by 1.06 ± 0.53 cm (P testosterone group had this complication (P > 0.05). There were three patients (8.3 %) with diverticula in group 2 and three patients (8.9 %) with this complication in group 1 (P > 0.05). None of our patients had signs or symptoms of meatal stenosis, glanular dehiscence, or residual chordee in both groups. Finally, there was a significant difference between the overall reoperation rates of group 2 (14 patients, 38.9 %) and group 1 (five patients, 14.7 %, P testosterone undecanoate was effective in improving the temporary penile growth and decreasing the surgical complications in children with microphallic hypospadias.

    Sativex® (GW Pharmaceuticals PLC, Porton Down, UK; Laboratorios Almirall, SA, Barcelona, Spain), a cannabinoid oromucosal spray containing a 1:1 ratio of 9-δ-tetrahydrocannabinol and cannabidiol, has been licensed in Germany since July 2011 as add-on therapy for moderate-to-severe multiple sclerosis (MS) treatment-resistant spasticity symptoms. The 'MOVE 2' study evaluated clinical outcomes, treatment satisfaction, quality of life (QoL) and provision of care in MS patients with spasticity receiving Sativex in everyday clinical practice. Data from 300 patients were collected from 42 specialized MS centers across Germany and were available for this analysis. Assessments, including the MS spasticity 0-10 numerical rating scale, modified Ashworth scale, patients' and physicians' clinical impressions, and QoL scales were rated at baseline and at 1 and 3 months after starting treatment with Sativex. Sativex provided relief of MS-related spasticity in the majority of patients who were previously resistant to treatment. In addition, clear improvements were noted in MS spasticity-associated symptoms (e.g., sleep quality, bladder function and mobility), activities of daily living and QoL. Sativex was generally well tolerated. The majority of patients (84%) reported no adverse events, and there was only a limited risk of serious adverse reactions. Furthermore, based on data from Sativex clinical trials, a Markov model-based analysis has shown that Sativex is a cost-effective treatment option for patients with MS spasticity in Germany.

    Full Text Available In the present paper, duplex WC-Co/NiCrAlY coating is coated onto Ti6Al4V substrate and vacuum heat treatment is employed to investigate the corrosion behavior of heat treated samples as well as Ti6Al4V substrate for comparison. In this duplex coating system, High Velocity Oxy Fuel (HVOF process is used to deposit NiCrAlY interlayer with a constant thickness of 200 μm and WC-Co ceramic top layer with varying thickness of 250 μm, 350 μm and 450 μm deposited by Detonation Spray (DS process. Different heat treatment temperatures (600–1150 °C were employed for the coated samples to study the microstructure and the effect on corrosion resistance of the duplex coatings. Potentiodynamic polarization tests were carried to investigate the corrosion performance of duplex coated heat treated samples and the substrate in Ringer’s solution at 37 °C and prepared the pH to 5.7. The microstructure upon corrosion after heat treatment was characterized by SEM analysis to understand the corrosion behavior. The results disclosed that at all heat treatment temperatures, all the coated samples exhibited better corrosion resistance than the base substrate. However, during 950 °C and 1150 °C heat treatment temperatures, it was observed highest corrosion potential than 600 °C and 800 °C. The 350 μm thickness, coated sample exhibited highest corrosion resistance compared to other two coated samples and the substrate at all heat treatment temperatures.

  15. Is immunotherapy an opportunity for effective treatment of drug addiction?

    Zalewska-Kaszubska, Jadwiga

    2015-11-27

    Immunotherapy has a great potential of becoming a new therapeutic strategy in the treatment of addiction to psychoactive drugs. It may be used to treat addiction but also to prevent neurotoxic complications of drug overdose. In preclinical studies two immunological methods have been tested; active immunization, which relies on the administration of vaccines and passive immunization, which relies on the administration of monoclonal antibodies. Until now researchers have succeeded in developing vaccines and/or antibodies against addiction to heroin, cocaine, methamphetamine, nicotine and phencyclidine. Their effectiveness has been confirmed in preclinical studies. At present, clinical studies are being conducted for vaccines against nicotine and cocaine and also anti-methamphetamine monoclonal antibody. These preclinical and clinical studies suggest that immunotherapy may be useful in the treatment of addiction and drug overdose. However, there are a few problems to be solved. One of them is controlling the level of antibodies due to variability between subjects. But even obtaining a suitable antibody titer does not guarantee the effectiveness of the vaccine. Additionally, there is a risk of intentional or unintentional overdose. As vaccines prevent passing of drugs through the blood/brain barrier and thereby prevent their positive reinforcement, some addicted patients may erroneously seek higher doses of psychoactive substances to get "high". Consequently, vaccination should be targeted at persons who have a strong motivation to free themselves from drug dependency. It seems that immunotherapy may be an opportunity for effective treatment of drug addiction if directed to adequate candidates for treatment. For other addicts, immunotherapy may be a very important element supporting psycho- and pharmacotherapy. Copyright © 2015 Elsevier Ltd. All rights reserved.

    OBJECTIVE: To determine incidence and patient characteristics of women with uterine rupture during singleton births at term without a previous caesarean delivery. STUDY DESIGN: Population based cohort study. Women with term singleton birth, no record of previous caesarean delivery and planned...... vaginal delivery (n=611,803) were identified in the Danish Medical Birth Registry (1997-2008). Medical records from women recorded with uterine rupture during labour were reviewed to ascertain events of complete uterine rupture. Relative Risk (RR) and adjusted Relative Risk Ratio (aRR) of complete uterine...... rupture with 95% confidence intervals (95% CI) were ascertained according to characteristics of the women and of the delivery. RESULTS: We identified 20 cases with complete uterine rupture. The incidence of complete uterine rupture among women without previous caesarean delivery was about 3...

    To study the efficacy of growth hormone given to severely burned children from discharge to 12 months after burn and for 12 months after the drug was discontinued. We have previously shown that low-dose recombinant human growth hormone (rhGH), given to children after a severe thermal injury, successfully improved lean muscle mass, bone mineral content, and growth. The aim of the present study was to investigate long-term functional improvements after treatment. Forty-four pediatric patients with over 40% total body surface area burns were studied for 24 months after burn. Patients were randomized to receive either rhGH (0.05 mg/kg body weight) or placebo. Height, weight, body composition, serum hormones, resting energy expenditure, cardiac function, muscle strength, and number of reconstructive procedures performed were measured during rhGH treatment and for 12 months after treatment was discontinued. Statistical analysis used Tukey's multiple comparison test. Significance was accepted at P < 0.05. Height, weight, lean body mass, bone mineral content, cardiac function, and muscle strength significantly improved during rhGH treatment compared with placebo (P < 0.05). This treatment significantly increased GH, IGF-I, and IGFBP-3, whereas serum cortisol decreased (P < 0.05). The number of operative reconstructive procedures was significantly lower with rhGH (P < 0.05). Improvements in height, bone mineral content, and IGF-1 concentrations persisted after rhGH treatment (P < 0.05). No side effects with rhGH were observed. Administration of rhGH for 1 year after burn was safe and improved recovery. These salutary effects continued after rhGH treatment was discontinued.

    Perovskite photovoltaics have recently come to prominence as a viable alternative to crystalline silicon based solar cells. In an effort to create consistent and high-quality films, we studied the effect of various annealing conditions as well as the effect of pyridine vapor treatment on mixed halide methylammonium lead perovskite films. Of six conditions tested, we found that annealing at 100 degree Celsius for 90 minutes followed by 120 degree Celsius for 15 minutes resulted in the purest perovskite. Perovskite films made using that condition were treated with pyridine for various amounts of time, and the effects on perovskite microstructure were studied using x-ray diffraction, UV-Vis spectroscopy, and time-resolved photoluminescence lifetime analysis (TRPL). A previous study found that pyridine vapor caused perovskite films to have higher photoluminescence intensity and become more homogenous. In this study we found that the effects of pyridine are more complex: while films appeared to become more homogenous, a decrease in bulkphotoluminescence lifetime was observed. In addition, the perovskite bandgap appeared to decrease with increased pyridine treatment time. Finally, X-ray diffraction showed that pyridine vapor treatment increased the perovskite (110) peak intensity but also often gave rise to new unidentified peaks, suggesting the formation of a foreign species. It was observed that the intensity of this unknown species had an inverse correlation with the increase in perovskite peak intensity, and also seemed to be correlated with the decrease in TRPL lifetime.

    Differences between therapists in their average outcomes (i.e., therapist effects) have become a topic of increasing interest in psychotherapy research in the past decade. Relatively little work, however, has moved beyond identifying the presence of significant between-therapist variability in patient outcomes. The current study sought to examine the ways in which therapist effects emerge over the course of time in psychotherapy. We used a large psychotherapy data set (n = 5828 patients seen by n = 158 therapists for 50,048 sessions of psychotherapy) and examined whether outcomes diverge for high-performing (HP) and low-performing (LP) therapists as treatment duration increases. Therapists accounted for a small but significant proportion of variance in patient outcomes that was not explained by differences between therapists' caseload characteristics. The discrepancy in outcomes between HP and LP therapists increased as treatment duration increased (interaction coefficient = 0.071, p < .001). In addition, patients' trajectories of change were a function of their therapist's average outcome as well as the patient's duration of treatment (interaction coefficient = 0.060, p = .040). Indeed, patterns of change previously described ignoring between-therapist differences (e.g., dose-effect, good-enough level model) may vary systematically when disaggregated by therapist effect.

    Treatment options are limited for HIV-1-infected individuals who have received extensive previous antiretroviral therapy. ETV has shown significant clinical benefits in treatment-experienced HIV-1+ patients with antiretroviral resistance. The aim of this study was to evaluate the effectiveness of ETV plus optimized background regimen in real-life conditions in a cohort of highly HIV-1 antiretroviral-experienced patients. Retrospective cohort of treatment-experienced HIV-1-infected adults with virological failure who started therapy with an ETV-containing regimen. The effectiveness was evaluated using HIV-1 RNA viral load and changes in CD4+ cell count after 48 weeks of treatment. Forty-two patients ≥ 16 years of age were included; 74% were men, and the median age was 45 years (IQR 41-53). All participants had prior non-nucleoside reverse transcriptase inhibitor use (55% nevirapine, 83%, efavirenz, and 28% both). Baseline median HIV-1 RNA viral load was 15,598 copies/mL (IQR 2651-84,175) and CD4+ cell count was 276 cells/mL (IQR 155-436). After 48 weeks of treatment, 90.5% (95% CI 78-96) of patients had HIV-1 RNA viral load treatment to a median of 407 cells/mL (IQR 242-579); p HIV-1 RNA viral load ≥ 100,000 copies/mL (OR 7.6; 95% CI 1.2-44.80; p = 0.025). Our study provides clinically important evidence of the effectiveness and safety of ETV in highly antiretroviral-experienced HIV-1-infected patients.

    Background Psychological distress is the major comorbidity among tuberculosis (TB) patients. However, its magnitude, associated factors, and effect on treatment outcome have not been adequately studied in low-income countries. Objective This study aimed to determine the magnitude of psychological distress and its effect on treatment outcome among TB patients on treatment. Design A follow-up study was conducted in Addis Ababa, Ethiopia, from May to December 2014. Patients (N=330) diagnosed with all types of TB who had been on treatment for 1–2 months were enrolled consecutively from 15 randomly selected health centers and one TB specialized hospital. Data on sociodemographic variables and economic status were collected using a structured questionnaire. The presence of psychological distress was assessed at baseline (within 1–2 months after treatment initiation) and end point (6 months after treatment initiation) using the 10-item Kessler (K-10) scale. Alcohol use and tobacco smoking history were assessed using WHO Alcohol Use Disorder Identification Test and Australian Smoking Assessment Checklist, respectively. The current WHO TB treatment outcome definition was used to differentiate the end result of each patient at completion of the treatment. Results The overall psychological distress was 67.6% at 1–2 months and 48.5% at 6 months after treatment initiation. Multiple logistic regression analysis revealed that past TB treatment history [adjusted odds ratio (AOR): 3.76; 95% confidence interval (CI): 1.67–8.45], being on anti-TB and anti-HIV treatments (AOR: 5.35; 95% CI: 1.83–15.65), being unmarried (AOR: 4.29; 95% CI: 2.45–7.53), having alcohol use disorder (AOR: 2.95; 95% CI: 1.25–6.99), and having low economic status (AOR: 4.41; 95% CI: 2.44–7.97) were significantly associated with psychological distress at baseline. However, at 6 months after treatment initiation, only being a multidrug-resistant tuberculosis (MDR-TB) patient (AOR: 3.02; 95% CI

    Background. Breast cancer is the most frequent malignant disease among women world wide. Survival has been improving leading to an increasing number of breast cancer survivors, in the US estimated to about 2.6 million. Material and methods. The literature was reviewed with focus on data from the Nordic countries. Results. Local therapies such as breast cancer surgery and radiotherapy may cause persistent pain in the breast area, arm, and shoulder reported by 30-50% of patients after three to five years, lymphedema in 15-25% of patients, and restrictions of arm and shoulder movement in 35%. Physiotherapy is the standard treatment for the latter while no pain intervention trials have been published. Chemotherapy may cause infertility and premature menopause, resulting in vasomotor symptoms, sexual dysfunction, and osteoporosis, which are similar to the side effects of endocrine treatment in postmenopausal women. Awareness of cardiotoxicity is needed since anthracyclines, trastuzumab, and radiotherapy can damage the heart. Breast cancer survivors have an increased risk of a major depression and far from all receive adequate anti-depressive treatment. Other psychological symptoms include fear of recurrence, sleep disturbances, cognitive problems, fatigue, and sexual problems. Discussion. To improve rehabilitation, specific goals have to be formulated into national guidelines and high priority directed towards research into developing and testing new interventions for alleviating symptoms and side effects experienced by breast cancer survivors

    This study aimed to evaluate the effectiveness of ivermectin on the treatment of bovine cutaneous papillomatosis. Twenty-four Holstein calves between 9 and 17 months of age with cutaneous papillomatosis were placed into three groups with six in group I, and nine in groups II and III. Group I served as a control group and received no treatment. Ivermectin at a dose of 0.2mg/kg was administered subcutaneously as a single dose to the animals in Group II and twice with 15 days intervals to animals in Group III. The first ivermectin application was considered as the 0th day Animals were monitored at 15 days intervals up to 3 months. No remission was observed in the control group (Group I). In Group II eight out of nine animals (88.8%) and in Group III seven out of nine animals (77.7%) showed complete recovery within 3 month observation period. It was concluded that ivermectin, as either single or double dose applications, is effective as a treatment for cutaneous papillomatosis.

    Full Text Available Preliminary findings support the potential of yoga as a complementary treatment of depressed patients who are taking anti-depressant medications but who are only in partial remission. The purpose of this article is to present further data on the intervention, focusing on individual differences in psychological, emotional and biological processes affecting treatment outcome. Twenty-seven women and 10 men were enrolled in the study, of whom 17 completed the intervention and pre- and post-intervention assessment data. The intervention consisted of 20 classes led by senior Iyengar yoga teachers, in three courses of 20 yoga classes each. All participants were diagnosed with unipolar major depression in partial remission. Psychological and biological characteristics were assessed pre- and post-intervention, and participants rated their mood states before and after each class. Significant reductions were shown for depression, anger, anxiety, neurotic symptoms and low frequency heart rate variability in the 17 completers. Eleven out of these completers achieved remission levels post-intervention. Participants who remitted differed from the non-remitters at intake on several traits and on physiological measures indicative of a greater capacity for emotional regulation. Moods improved from before to after the yoga classes. Yoga appears to be a promising intervention for depression; it is cost-effective and easy to implement. It produces many beneficial emotional, psychological and biological effects, as supported by observations in this study. The physiological methods are especially useful as they provide objective markers of the processes and effectiveness of treatment. These observations may help guide further clinical application of yoga in depression and other mental health disorders, and future research on the processes and mechanisms.

  8. Effectiveness of gefitinib in combination with methotrexate in the treatment of ectopic pregnancy.

    Medical management for ectopic pregnancy is subject to substantial variations with different protocols and various routes of administration. Regardless the protocol used, methotrexate is currently the medical treatment of choice for ectopic pregnancy. The risk of a rescue surgery is a main concern. Recently, some studies suggested combining gefitinib and methotrexate to improve medical treatment and to decrease the need for reinjection and for additional surgery. Gefitinib is an orally administered EGF receptor-tyrosine kinase inhibitor. For tubal ectopic pregnancy, median recovery time was shorter after combination treatment with gefitinib and methotrexate. Toxicity reported with combination treatment was acneiform rash in 67% of cases and diarrhea in 42%. They were always transient and are known side effects of gefitinib previously described in lung cancer. These preliminary results are very promising but need to be explored further before wide distribution. For ectopic pregnancy, combining treatment seems to be interesting but results of the first randomized trial have to be evaluated first. For other indications, such as non-tubal ectopic pregnancy or choriocarcinoma, randomized studies are needed before wide use of the combination in current practice.

    In the present study, we examined the effects of acute treatment with paroxetine on the consumption of cigarette smoking and caffeine in 65 patients who met the DSM-IV criteria for major depressive disorder (M/F: 28/37, age: 48 +/- 15 years). Plasma levels of cotinine or caffeine were analysed using high-performance liquid chromatography (HPLC). The amount of cigarette smoking and plasma levels of cotinine, but not caffeine, decreased 4 weeks after paroxetine treatment. There was no difference between smokers and nonsmokers with respect to their response to paroxetine treatment. In addition, plasma 3-methoxy-4-hydroxyphenylglycol (MHPG) levels in responders to paroxetine treatment was higher than those in nonresponders, and there was a negative correlation between the changes in plasma MHPG levels and the changes in Hamilton rating scale for depression (Ham-D) scores before and 4 weeks after paroxetine administration. These results suggest that paroxetine has the potential to reduce the amount of cigarette smoking in depressed smokers, and we reconfirmed our previous results that depressed patients with higher plasma MHPG levels had better response to paroxetine treatment than those with lower plasma MHPG levels using larger depressed samples.

    Full Text Available Abstract Introduction Autism is complex neuro-developmental disorder which has a symptomatic diagnosis in patients characterized by disorders in language/communication, behavior, and social interactions. The exact causes for autism are largely unknown, but is has been speculated that immune and inflammatory responses, particularly those of Th2 type, may be involved. Thiazolidinediones (TZDs are agonists of the peroxisome proliferator activated receptor gamma (PPARγ, a nuclear hormone receptor which modulates insulin sensitivity, and have been shown to induce apoptosis in activated T-lymphocytes and exert anti-inflammatory effects in glial cells. The TZD pioglitazone (Actos is an FDA-approved PPARγ agonist used to treat type 2 diabetes, with a good safety profile, currently being tested in clinical trials of other neurological diseases including AD and MS. We therefore tested the safety and therapeutic potential of oral pioglitazone in a small cohort of children with diagnosed autism. Case description The rationale and risks of taking pioglitazone were explained to the parents, consent was obtained, and treatment was initiated at either 30 or 60 mg per day p.o. A total of 25 children (average age 7.9 ± 0.7 year old were enrolled. Safety was assessed by measurements of metabolic profiles and blood pressure; effects on behavioral symptoms were assessed by the Aberrant Behavior Checklist (ABC, which measures hyperactivity, inappropriate speech, irritability, lethargy, and stereotypy, done at baseline and after 3–4 months of treatment. Discussion and evaluation In a small cohort of autistic children, daily treatment with 30 or 60 mg p.o. pioglitazone for 3–4 months induced apparent clinical improvement without adverse events. There were no adverse effects noted and behavioral measurements revealed a significant decrease in 4 out of 5 subcategories (irritability, lethargy, stereotypy, and hyperactivity. Improved behaviors were inversely

    Psychological and pharmacological interventions for binge-eating disorder have previously demonstrated efficacy (compared with placebo or waitlist control); thus, we aimed to expand that literature with a review of comparative effectiveness. We searched MEDLINE,® EMBASE,® Cochrane Library, Academic OneFile, CINAHL® for binge-eating disorder treatment articles and selected studies using predetermined inclusion and exclusion criteria. Data were sufficient for network meta-analysis comparing two pharmacological interventions; psychological interventions were analysed qualitatively. In all, 28 treatment comparisons were included in this review: one pharmacological comparison (second-generation antidepressants versus lisdexamfetamine) and 26 psychological comparisons. Only three statistically significant differences emerged: lisdexamfetamine was better at increasing binge abstinence than second-generation antidepressants; therapist-led cognitive behavioural therapy was better at reducing binge-eating frequency than behavioural weight loss, but behavioural weight loss was better at reducing weight. The majority of other treatment comparisons revealed few significant differences between groups. Thus, patients and clinicians can choose from several effective treatment options.

    The report presents the results of a study on the relative cost of energy from a nominal 1000 Mwe nuclear steam electric generating plant using either dry or evaporative cooling at four sites in the United States: Rochester, New York; Sheridan, Wyoming; Gallup, New Mexico and Dallas, Texas. Previous studies have shown that because of lower efficiencies the total annual evaluated costs for dry cooling systems exceeds the total annual evaluated costs of evaporative cooling systems, not including the cost of water. The cost of water comprises the cost of supplying the makeup water, the cost of treatment of the makeup and/or the circulating water in the tower, and the cost of treatment and disposal of the blowdown in an environmentally acceptable manner. The purpose of the study is to show the effect of water costs on the comparative costs of dry and evaporative cooled towers

    Multiple schedules with signaled periods of reinforcement and extinction have been used to thin reinforcement schedules during functional communication training (FCT) to make the intervention more practical for parents and teachers. We evaluated whether these signals would also facilitate rapid transfer of treatment effects across settings and therapists. With 2 children, we conducted FCT in the context of mixed (baseline) and multiple (treatment) schedules introduced across settings or therapists using a multiple baseline design. Results indicated that when the multiple schedules were introduced, the functional communication response came under rapid discriminative control, and problem behavior remained at near-zero rates. We extended these findings with another individual by using a more traditional baseline in which problem behavior produced reinforcement. Results replicated those of the previous participants and showed rapid reductions in problem behavior when multiple schedules were implemented across settings. © Society for the Experimental Analysis of Behavior.

    While it is well understood that individuals with aphasia have difficulty with discourse comprehension, very few studies have examined the nature of discourse comprehension deficits in aphasia and the potential for improvement in discourse comprehension after rehabilitation. To address the first goal, we previously developed the Test of Syntactic Effects on Discourse Comprehension (TSEDC), which provides a measure of the extent to which a participant's sentence comprehension ability aids in comprehending passages (Levy et al., 2012). The goal of this study was to examine the effect of a sentence comprehension treatment on the TSEDC to assess if training participants to understand sentences of different syntactic complexity would improve their ability to understand passages that vary by their level of syntactic complexity. Forty participants with aphasia received sentence comprehension treatment using one of two syntactic comprehension tasks: object manipulation (OM) or sentence to picture matching (SPM). The dependent measure was improved sentence comprehension of one sentence type in one task-related protocol, with the order of task and structure counterbalanced across participants. Before and after treatment, participants also completed a self-paced auditory story comprehension task which involved 9 passages that contained either semantically reversible canonical sentences (simple passages) or semantically reversible noncanonical sentences (complex passages). At the end of each passage, participants were asked explicit or implicit questions about the story. Accuracy and reaction times were measured for each patient for each story before and after treatment. Analysis of the treatment data revealed that participants improved in their ability to understand trained sentences (both in terms of effect size and percent change on trained structure), irrespective of whether the trained task was SPM or OM. There was no significant relationship between treatment

    Infliximab is effective for induction and maintenance of response in patients with moderate to moderately severe ulcerative colitis. Previous cost analyses of infliximab treatment for ulcerative colitis used models of colectomy vs infliximab and response rates derived from early clinical trials. In real life, therapeutic options are more complex; patients frequently choose to remain in an unwell state rather than undergo colectomy, and rates of response to infliximab are generally higher than those reported from clinical trials. We evaluate the real-life cost-effectiveness of infliximab for treatment of ulcerative colitis where infliximab was readily available compared with not available, causing patients to remain in unwell states. We constructed a Markov model to simulate disease progression of patients with moderate or moderately severe ulcerative colitis who depended on corticosteroids and/or did not respond to thiopurine therapy. Utility scores and transition probabilities between health states were determined by using data from randomized controlled trials and real-life rates published by expert inflammatory bowel disease centers. Health care costs were obtained from the Ontario Case Costing Initiative and the Alberta Health Schedule of Medical Benefits documents. The incremental cost-effectiveness ratios for infliximab treatment of ulcerative colitis were $79,000 and $64,000 per quality-adjusted life year, compared with ongoing medical therapy, at 5-year and 10-year treatment time horizons, respectively. By using real-life response rates and patients' preference to avoid colectomy, infliximab therapy is a cost-effective strategy at a willingness-to-pay threshold of $80,000 for treatment of ulcerative colitis.
